This is surprising.  I just manually verified the driver against the
cx700 programming manual, and it seems to do the right thing.  Lacking
access to a cx700 board right now, I cannot perform an actual test.

Where exactly is the bug about the wrong register that you mentioned?
I'd rather fix that ASAP.

good to know.  Seems like I need to get access to a CX700 based board.

JFYI: I wrote one but it doesn't work on the vx800/vx855, and VIA is currently
trying to figure out why.

I think the CPU just claims to report it but in reality doesn't... this was
made to make some proprietary software happy, AFAIR.
