Hmm. I have the same problem with a Vaio PCG-R505TFP. Looking at your
dmesg it looks like it is basically the same motherboard chipset (ICH3-based)
but with different processor (mine's a PIII-M 1200).

Anyway, I did a little bit of snooping and found that pcm0's interrupt doesn't
seem to be getting as far as the interrupt handler (via judicious use of printf()).

The symptom I have is is that xmms doesn't work at all, and ogle works for about
one samples worth of data (probably because pcm0 and the DVD-ROM on firewire
share irq 9).

Have you tried booting the machine with ACPI disabled? All mine does is panic
in what might be the PNPBIOS code. I expect that if/when you use Windows on the
the machine the sound works fine?

I can also supply fairly verbose boot messages (with lotsa ACPI debug) and
extracted DSDT files if necessary (although not until tomorrow).

(Personally I blame interrupt routing, but I have no evidence at all to
back that up).
