Hi,
I have this notebook too and it works fine linux (except for the modem).
If you cant install some distributions you may have a USB-device plugged in the inner or the middle USB-port. Only use the outer one (the one at the left side).
The bios of the Amilo A 7600 is buggy so everytime X is started with 3D enabled the Amilo crashes and you get a black screen.
All distributions containing X.org 6.8.1 or better and Kernel 2.6.x (or 2.4.23 and better)
support 3D on IGP 320M. Some distributions like Fedora Core 3 try to enable 3D by default if they detect a IGP 320M and this results in a black screen.
The reason for the problems with the USB-mouse is also the buggy bios. They occur with kernel 2.4.27 and newer and newer 2.6.x - kernels. But the outer USB-port is usable everytime.
Solutions
1. If you do not need 3D disable it in your xorg.conf
Comment out the line:
Load "dri"
For this you have to boot in runlevel 3, so that X is not started automatically.
2. If you want 3D and/or you want to use all USB-ports:
You have to inlude a custom DSDT-table in the boot process.
This is somewhat tricky so I cant explain it in a few words.
See:
http://acpi.sourceforge.net/dsdt/index.php # genereral things about DSDT
http://groups.yahoo.com/group/amilo # Yahoo group, main topic is Amilo A 7600 with linux
there you can get help and a well tested
DSDT-patch
For touchpad:
-is the psmouse-module loaded? Sometimes it does not load automatically (SuSE 9.2)
-try booting with
i8042.nomux
as a bootparameter
For PS2 devices:
-make sure your bios is at least 1.0.7, but do not use the latest 1.10 if you want a quiet
notebook.
1.0.9 works good.
If you already have questions about the Amilo just ask.
