i810fb problems with 2.5.66-bk10

[Siim Vahtre]

First of all, the cursor is playing fool. Sometimes it disappears when I
am writing and sometimes it looks normal. Pretty annoying.

And when I did:

modprobe i810fb mtrr=1 accel=1 xres=640 yres=480 hsync1=30 hsync2=60 vsync1=50 vsync2=100 bpp=16 dcolor=1
modprobe fbcon

I got:

It didn't stop working, though... and everything else (like switching to X
and back) looks nice. (except the cursor..)
