Oh, 1.0.15?  Whan an old version.  Could you check whether the
latest HG version (or at least 1.0.16) works?
Or, 2.6.25 kernel, which includes most of 1.0.16 stuff.

Depends.  Somethings it's controlled via hd-audio but sometimes over
ACPI.  Anyway, you have to try the latest version (HG version) so that
you can test any patches over it.
