After a while, also 0x101 started to work, until I stopped virtual 
machine for a while and started it :|, need to diagnose why this 
happened... but not now.

I have made simple modification from vga terminal to vesafb terminal. It 
is far from being good or complete implementation. It is only provided 
to receive some feedback how it works and for other comments. Formatting 
of source code is probably not following grub 2 coding conventions.

Complete source for grub2 and my modifications can found from here:
http://jumi.lut.fi/~vjaaskel/grub2/grub2-20050710-vesafb.tar.gz

I have modified (at least) following files:
grub2/conf/i386-pc.rmk
grub2/kern/i386/startup.S
grub2/include/grub/machine/vbe.h
grub2/term/i386/pc/vesafb.c

To test it, run normal process of compiling grub2 (configure ; make ; ...)

After booting up:
insmod terminal
insmod vesafb
vbe_list_modes
(pick one listed mode)
set vbe_mode=<picked mode>
terminal vesafb

On startup.S there are also some VBE calls that are not yet implemented, 
so if you are going to play with it, check those from there first.

After I have some time to implement those, I could see what needs to be 
done elsewhere to really start using graphical modes and then start 
discussion on it.
