I just installed the latest stock Fedora kernel for kicks,
2.6.9-1.681_FC3 (using it's own ALSA modules, not sure what version)
and HDSPmixer now works.  The outputs show up and peak meters fly the
way they should.

Unfortunately this kernel is probably not usable without all of
Fernando's lowlat goodies, realcap, etc...I was finally getting
excellent performance with JACK et al on

Is there a newer 2.6.9 kernel rpm (srpm ideally) with lowlat, etc
applied out there for testing?  I didn't see anything beyond in Planet SRPMS.
