I'll make one now. The AC97 driver needs it anyway, later, plus some
definitions are missing for PSC control.. also only used by the AC97
driver for now, but still probably quite important (or just hardcoded
elsewhere).

We just worked around a crash bug (somehow..) but now we get no audio.
I'm not going to submit it to them until we can actually get sound
out of the damn thing..
