Apparently I lied...

Righto, something magic happened and the machine now outputs
sound without any problems.

The only thing that I can really think of that might have b
rought this about (short of me screwing something up - which I
don't believe I did - or some strange hardware fault) is that
he did attempt to boot into a vanilla Windows XP Professional
installation (unsuccessfully, mind you) between our testing and
the sound problem magically disappearing. The machine has a
hardware volume adjuster thingy that isn't just an analog
volument control (i.e.: It's the kind where some software is
required to handle the thing), so perhaps the hardware volument
was set to an aduible level by the XP boot? ...I hate things
fixing themselves magically!

Booting with the unpatched kernel leads to no sound, so Pyun's
patch appears to have done the trick!
