Yep. It probably doesn't happen on x86, since the int10 stuff
initializes the card with the onboard bios. Using a x86 emulator in X to
run this bios might be a solution.

Ho. definitively some registers who are bad. It has been a long time
since i have looked at the pm2 specs (kind of 98ish i think) though.
Maybe you could get hand of the free TI-pm2 specs and look for yourself ?
You would dump all the possible registers, and see which one is
different. Enabling debugging in the glint driver would also do. You can
safely run no-accel on these for the tests, as this is definitively not
an accel issue, but a video out/ramdac one.

Any color problem ?
