Wow, okay -- I replaced my PWS433a's motherboard with one from a
friend since his audio wasn't working and mine was.  It seems that
the new motherboard reproduces your problem every time and so I
came up with a quick work-around that seems to do away with it and
checked it into current.

Could you see if sys/dev/pci/tga.c version 1.32 eliminates this
problem for you?
