Try these values and check what is the biggest resolution you graphics
card/monitor is supporting.
Then hardcode that value in /boot/grub/menu.lst if you are using grub
or /etc/lilo.conf if you are using lilo.

concentrate on /device_drivers/graphics and
/device_driver/character_devices/agpgart_support while configuring
kernel. enable most of the options in this section(except enabling
graphics card support which is not isntalled on your system).
