Hmm.. sound works just fine for me on my X61s (model #7668-CTO)
running 2.6.24.
I do have this private patch applied --- maybe it makes a difference
for you? I don't think it should make a difference, but....

hda_intel suspend latency: shorten codec read
not sleeping for every codec read/write but doing a short udelay and

The patch also fixes the unexpected codec-connection errors that
happen more often in the new power-save mode:

This had been applied, and then reverted due to problems. See commit
