AlSA.

This was a helpful tip, and it worked. Actually, it didn't fully restart
when I used this command, but it gave the pids of the processes blocking
it. From there, I could kill the pids, and then cleaning restart 'alsa'. 

This allowed me to try to new things much faster than doing a fall
restart each time!

What worked for me was to "not" use KLaptop to suspend. Instead, I use
Fn-F4. For some reason, this causes Mandriva's suspend related shell
scripts to run, when KLaptop does not. 

Thanks again to both you who replied!

In summary:
  Kernel 2.6.12
  ACPI
  Set RESTORE_SOUND=yes in /etc/sysconfig/suspend
  Use Fn-F4 to suspend
