Well, I haven't gotten as far as dumping the registers, but I came
across Permedia2VPreInit in pm2v_dac.c, and forced it to call
Permedia2VPreInitSecondary(pScrn) unconditionally.

I also changed a few things seemingly related to linux-kernel-headers to
get the thing to compile, and it improved the situation.  Now there is a
mild amount of distortion and flicker.  The really bad part is that if I
drag an open window, it will turn into a block of noise, somewhat
related to the colors of the root window.  Also, X now detects 8 megs of
memory on that card.
