i had patched my kernel-source - 2.6.11 for debian logo and custom kernel also works.but debian logo was not displayed properly.i searched web but no source.see my grub:
title Debian GNU/Linux, kernel 2.6.11alsa
root (hd0,6)
kernel /boot/vmlinuz-2.6.11alsa root=/dev/sda7 ro sda=scsi video=vesafb:ywrap,mtrr vga=788
initrd /boot/initrd.img-2.6.11alsa
savedefault
boot
what was wrong?i have my display at 800*600 so vga=788 is OK i think.
Also please explain other variables ywrap,mtrr
