Yeah, I also tried rc6.

I've not tried removing the wifi card.

One thing I did was to modify the kernel code to force a speaker beep
upon resuming from sleep.  This did not work.  I noticed the code which
is triggered by s3_beep is run AFTER the kernel first perform some
consistency checks.  So if the consistency checks fail, the kernel does
not run the code to make the speaker beep. I added code to perform the
beeps BEFORE these checks but I still heard no beep.

I see two possibilities: 1) there is just no functional legacy PC
speaker hardware on the board or 2) the kernel never regains control
after the hardware resumes operations.
