xorg.conf - video && touchpad problem * (Dell C640)

Hey there,
Right now i have my Dell C640 computer set up and i have a few problems with the the xorg.conf file... everything runs alright just a few nuisances which i would really like to fix up.

Distr - Ubuntu Warty 5.04

Problem #1
Touchpad -- i have synaptics set up and everything (Ubuntu auto installed that) but i'm having trouble with the double tapping -- when i'm typing which is just purely annoying cause it takes off focus, randomly moves my point of typing back a few lines or overwrites several lines... so far i've added the "MaxTapTime" "0" to the xorg... which supposedly should've fixed it but it doesn't seem to work... i've tried running various synclient things and it usually gives me this error:

Can't access shared memory area. SHMConfig disabled?

not sure how to 'enable' or allow acces... i've also tried to install qsynaptics tho it seems to only support XFree86... so i'm not too keen on doing that... yet...

Problem #2
Video -- overall my video works alrite... but according to the xorg file.. the auto detect has set my video card driver to "ATI Technologies, Inc. Radeon Mobility 9000 (M7 LW)", when in the ubuntu device manager and the bios it clearly says its 9500... not sure if thats a problem.. but occaisionally when shutting down or switching from X to consoles... ubuntu will freeze... and whatever colour i had on my Xwindow will slowly fade out (sorta like when logging out) except it passes grey... and inherently inverts the color... and it does this fadingly... sorta a 'cool' effect... except i gotta hard reset to do anything after that... not sure of thats directly related to my video driver... but i'm pretty sure its NOT suppose to do that...

so yah... my two nuisancish problems i have right now... that i'm dealing with by using more xterms than the consoles (kinda annoying..) and typing with a chequebook over my touch pad.. heh.. so if theres any better way to cope with this... long term (other than ductaping my chequebook to my laptop) i'd glady appreciate it

here's my xorg.conf... hope you can help -- thanks!

The SHMConfig error i can help you with. -- add Option "SHMConfig" "on" to your XOrg.conf file in the section about your synaptics Input
