Normal for now. No tux until I write the code. The white is due to a bug
in the upper framebuffer console system. I plan to fix that in the near
future. First I have port everything over.

I noticed. The mode did change for me but it locked up. Nothing was
recorded either. Since you are using serial console can you define
RIVAFBDEBUG in fbdev.c and send me your output.

My fault. I set the new RIVA driver to MSB mode for dealing with images.
The X server uses the opposite. I did that to reduce the amount of code in
the kernel driver. Unfortunely X is broken so I have to add back the extra
code again.

I attempted that one as well. It didn't work for me either.
