I briefly thought about scanning the Xorg.0.log - the VIA driver
helpfully logs which chipset it's found. But that's way too ugly to be
a good solution.
How about testing for an environment variable at runtime - e.g.
MYTHTV_CX700_WORKAROUNDS, and using the workarounds if it's found? It
won't be totally transparent for the end user, but it would be easier
for them than patching and rebuilding the software. And it would be
trivial to add to the code.
