Sometimes keys get stuck and other times simply don't work

I am using a laptop processor amd64, with an ATI Xpress 200 M and ubuntu 8.04

Sometimes when i am writing my keys get stuck.
Other times they simple don't work.

I disabled acpi, change locales and try different xorg.conf files. NOTHING WORKED!!!

Is impossible to work with a computer like this because sometimes, LIKE NOW :), you are trying to write and you simply can't.

Here is part of my dmesg output:
