Eureka! It works!
Outstanding!!!
The basic problem all along seems to be that fbdev sucks on alpha. It seems that any and all graphics operations don't work on the alpha (if someone else knows otherwise, please do tell). None of the various applications I could find that wrote to the framebuffer were able todisplay anything, including fbtv, fbi, mplayer, fbgs, ggi, svgalib, sdl,...
directfb works.
Confusingly, I no longer have boot penguins. But the VGA console still works and I can start X, now that the card is in the other slot. Andwho cares about fbdev when you have X? Also the "Devsel" error messagesI posted earlier are gone.

I briefly put a Matrox Milennium II in the CS20, and it DID display the video BIOS screen on bootup. The Marvel G200 I have does not, however. Maybe it's the card itself.
Don't know what to tell you. Are you running the marvel now and able to get
a video signal? Peter
