  So my mail was delayed do to a local mail problem... I think I have
answers to all of those questions.

could you run the following:
  lspci -vvv
  scanpci -v

... I'm curious what the 
  MAX_LAT   0x00  MIN_GNT 0x00  INT_PIN 0x01  INT_LINE 0x0b
are from scanpci (part of xutils package).  You will need to be root to
run scanpci but not lspci.

  The output will be a little long... I'm thinking that the pci card
might be locking down the bus for too long.  There are supposed to be
a way to limit how many cycles a pci device can hold the bus in a
continuous chunk.  I'm not sure exactly how to change the lengths right
now but figuring it out shouldn't take too long.

  Also have you tried playing sound via a bfp?
something like:
  mpg321 -s sound.mp3 | bfp
