[PlanetCCRMA] JACK 0.94 with RH9, 2.6.3 kernel, and Intel 810

Hello,

    I'm having some trouble getting JACK to start
(output appended at the end). It looks like it can't
find my sound card, which is actually the onboard
Intel 810. My hunch is that I'm not telling it how to
find the sound card correctly.

    I think I have ALSA working with OSS emulation, as
XMMS works fine. I compiled ALSA support into the
2.6.3 kernel. I have also installed alsa-lib-1.0.2 as
an rpm.

Suggestions?

Thanks,
Michael

Here's the output from JACK:
