Debian on Toshiba Satellite A70 sound, mouse, and video problems


I know I already posted this elsewhere, but thought that this forum might be more helpful since I run Debian.
I recently purchase a Toshiba Satellite A70 laptop, and am trying to run Debian Linux on it. However, I ran into a number of problems, I tried google but to no avail. Specifiically, I have:
no sound
my touchpad mouse does not work (I have a wireless mouse for now that works
perfectly, but I would enjoy being able to use the touchpad)
my resolution is only 1024x768. Since I have a widescreen capable of running
1280x800, I would like to be able to run at that resolution.

The only error I get is for my sound, when I startx I get an error saying /dev/dsp no such file or directory sound will be outputted to dev/null I believe. I have no idea what files I should include to help you guys solve my problem, much less who makes my soundcard, as Toshiba is less than helpful. --EDIT-- I got this from CNET, but it appears that Toshiba no longer carries my laptop anymore, even though I bought it from them about 2 months ago
CNET says this about my sound card: Audio codec - Realtek ALC250

The mouse and resolution problems aren't quite as severe, as I know I just need to edit my xf86 file correctly to get them to work, but I would appreciate it if anyone has a copy of theirs that I could look off of. Here is a short copy of mine:
--EDIT-- WOW... I'm such a n00b... On a hunch, to change my resolution all I did was manually edit the file so that in my Display section, instead of 1280x1024 I put 1280x800... I thought It would take more work than that. Amazing how simple that was!

For the sound problem, try installing alsa (apt-get install alsa-base), then run "alsaconf" script to configure your sound card.

The touchpad should work as a standard PS/2 mouse I think. Here is the device section for the mouse on my Dell laptop running Sarge. The touchpad and "eraser" pointer both work:
Section "InputDevice"
Identifier "Default Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/psaux"
Option "Protocol" "PS/2"
Option "Emulate3Buttons" "true"
Option "ZAxisMapping" "4 5"

Hey, thanks...

I've tried several things, including running alsaconf. It seems to find my sound card / driver (attixp, by the way, and I beleive it is using the Realtek ALC250 AC '97 chipset... not sure what that means), and says everything is fine, try running a mixer. Still, when I try to do that I get a /dev/dsp is missing.

--EDIT-- By going to KDE Control Center and changing the sound device under the "Hardware" Tab from "Auto-Detect" to "Advanced Linux Sound Architecture" (ALSA) I now get a different Sound error. The Error now reads "device: default can't be opened for playback (no such file or directory). The Auto-Detect still produces the old "/dev/dsp can't be opened for playback". I did an ls -l of my /dev directory, and there is no /dev/dsp. I followed some advice on another forum:

that recommends using # mknod /dev/dsp c 14 3
This creates /dev/dcp, but as far as i can tell I cannot access this device, maybe due to file permissions. it creates a crw-r--r-- 1 root root 14, 3 2005-10-13 16:08 /dev/dsp. This file is promptly destroyed at each reboot.

Also, I tried using your mouse config, I get an error from xserver that it can't find /dev/psaux. I believe this will work if i knew where my touchpad was located (/dev/mouse, /dev/input, etc), but I don't know where to find that info.

Here is my new (edited) XFree86-4 config:
# Working Wireless Mouse

Identifier "Wireless Logitech Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ImPS/2"
Option "Emulate3Buttons" "true"
Option "ZAxisMapping" "4 5"
