To be on the safe side, I did "modprobe tdfxfb" (which, incidentally, did some weird stuff to my screen while in console--see bottom).  MPlayer is still not working, though--when I try to open a movie by running "mplayer -vo tdfxfb filename", it says "tdfxfb: can't open /dev/fb0: Permission denied."  This despite the fact that my login is in the group that /dev/fb0 is in.

Maybe an inch and a half tall, and proportionally wide.  The font is a little squished, vertically, as well.  Everything else still works alright.  When I try loading the module in X-Window, the screen goes black permanantly.

You'd better compile it the kernel and not as module. And don't enable the vesa fb.
I never got it working as module.
