[tlinux-users:08475] linux for satellite a135-s4437

hi everyone!! i need some help with my toshiba.
I've installed Debian etch but the sound works worse than my windows 
vista. The difference of quality is huge. The kernel installed  is  
2.6.18, I try to compile my kernel and update to 2.6.20 but didn't work.
I've got the same problem with video, works but  the image see pixeled. 
I've got the i810 driver in my xorg.conf. I try different things  that i 
find in different forums, but nothing.
The last problem is the hot keys I've installed the packages of Debian 
for Toshiba and recompile the kernel but didn't works.
Is there any distro that works with this model of Toshiba? or any kind 
of measure to take?
thank you for help, and please excuse me English, I'm from Argentina,
