If you have performance problems in some games like Quake 3 or TCE / Enemy Territory, try to disable KMS.
The problem can also be with the mouse pointer (slowness, lag, delay or inacuracy).

Grub 2

Add nomodeset in /etc/default/grub then issue the command update-grub.

vi /etc/default/grub
GRUB_CMDLINE_LINUX="nomodeset"
update-grub

Grub 1

Add nomodeset at the end of the # kopt line, then issue command update-grub.

vi /boot/grub/menu.lst
# kopt=root=/dev/sda1 ro nomodeset
update-grub

Someone also told me that disabling KMS solved his Firefox javascript speed problem in Yahoo Mail.
