Can't change screen resolution past 800x600 (Debian Sarge)

I recently installed Debian Sarge but am unable to change the screen resolution past 800x600. When I try to change it with the gui, the highest possible choice is 800x600. Can anyone tell me what changes I need to make and to what files?

If you're using lilo you should have something like this in your /etc/lilo.conf file:

vga = 791
# Normal VGA console
# vga = normal
# VESA framebuffer console @ 1024x768x64k
# vga=791
# VESA framebuffer console @ 1024x768x32k
# vga=790
# VESA framebuffer console @ 1024x768x256
# vga=773
# VESA framebuffer console @ 800x600x64k
# vga=788
# VESA framebuffer console @ 800x600x32k
# vga=787
# VESA framebuffer console @ 800x600x256
# vga=771
# VESA framebuffer console @ 640x480x64k
# vga=785
# VESA framebuffer console @ 640x480x32k
# vga=784
# VESA framebuffer console @ 640x480x256
# vga=769
# End LILO global section
Where the vga=791 is the selected screen setting for my system... So long as I have frame buffering support enabled in my kernel.

If you make any adjustments to your /etc/lilo.conf file be sure to run lilo afterward, or you may have problems booting.

Make sure that you have compiled your kernel with support for your video card and monitor...

Forgive me if I'm completely off base...
