Hmm, so you say you can't boot a vanilla (unmodified) 2.6.34-rc4? Is
your problem fixed in the current git HEAD? The bisect procedure I
described shouldn't touch anything else than sound code, so SATA should
be unaffected. Anyway, you can skip unbootable or uncompilable versions
with

  $ git bisect skip

HTH,
