I had the same problem, here is what worked for me: apt-get install hwinfo
hwinfo --framebuffer Look at the Mode lines, find the one I want: Mode 0x0323: 1024x768 (+4096), 24 bits convert 0323 from base 16 to base 10 put result into menu.lst kernel line: vga=803 You don't need hwinfo to get the modes, you can set vga=ask and then convert the numbers you see to base 10. HTH...
