kgicon problems...

Today i decided to do a new try at kgicon.

First i compiled a fresh 2.1.115 with vgafb etc.

Then i compiled a clean vga kgicon.o 
(using the default 640x400x8, is this really possible in vga?)

Inserting gives a scrambled graphics mode and after a second or 
so it locks up.
The following oopses can be found in /var/log/messages:

The oops seems to be in fbcon_putcs (c01a5340).

Ok, the i tried the mystique driver. It locks solid (with a black
screen) on inserting.

Ok, maybe if i try vga in 320x200x8, that might work better.
No, new oops, this one also in fbcon_putcs:

Ok, this was on my Matrox Mystique running RH 5.1, and
linux 2.1.115 on a P200 MMX. 

Does anybody know what's happening?
