at half speed on the 8233A revision of the chipset. This implicitly
means no SPDIF for VIA8233A users.
o Make DXS3 the primary playback channel. It may be the only
universally supported channel with the assorted revisions of this
chipset.
o Add sysctl and handler for enabling s/pdif output from DXS3.

driver to attach to it to use shared resources of fm801 chip. The radio
driver itself will be committed later.

obviously wrong in -current also. MFC is forthcoming.

able to hear audio on ich2 m/b which was eventually found to be

is that some cards built around fm801 chip have the same device ID, only
have radio tuner onboard, but no sound capabilities. Therefore, with such
card inserted and `device pcm' in kernel the user has a big problem, as
the fm801 driver effectively hangs the machine when trying to initialise
nonexistent ac97 codecs (it does 500 retries with 1 second interval!).
It would be better if MediaForte's engeneers were smart enough to put
different device ID into such cards, but it isn't an option.

not run at the correct speed. It probably also eliminates the
need for the hacks/workarounds/sysctl's that were previously
devised to deal with this, but I will leave that for a different
time.
