I have something similar on one of my i386 boxes - it started
happenning after I took the Spider Tarantula S3 graphics board out,
and put in an old Orchid ProDesigned 2S video board.  Upon boot, the
Orchid announces that it has 1M video memory, although I'm not sure
that it does.  It gets to the fd probe, and does that fine, and then
jumps all over the screen with the output - it looks like it thinks
the screen is 40x12, in four different quadrants.  What I've found to
cure it is to get a lot of error messages written all over the screen,
so I log in (blind), and do an "mdir a:" with no floppy in the drive. 
The screen is fine after that, and I can run X on the screen with no
problems.  I had put it down to a funny in the old Orchid board.  I
don't get any messages on the speaker.

The interesting thing about this is the point at which it goes all
screwy - the fd message is displayed exactly 25 lines after the boot
prompt, so it's as if it's when it scrolls for the first time.

I'm not particularly bothered by this - this is just another data
