I may be way off, but the boot up scrolling sounds like the video card
is sending out PAL insted of NTSC. I have onboard video and can
configure either PAL or NTSC in the mb bios.  The default bios setting
is PAL, and with PAL, I get the scrolling you describe.  The colours
are also off.  No idea how to fix if a video card..

It also sounds like you may have your X settings incorrect.  Jarod has
his X settings for a MX400 in his howto. You might want to take a look
at it.
