I never had the falling asleep problem. For some reason, your
pmud either receives a sleep message from somebody, or incorrectly
thinks it got one...

I had a few lockups, most related to problems with the kernel
console code (when sleeping from console). I never had a lockup
in X but I know that some part of the kernel are quite fragile
regarding power management (USB for example).

Do you have any other device attached ? (like a PCMCIA card ?)

You probably need to alter your /etc/pwrctl script, yes. I don't
have mine at hand right now, I'll send it tomorrow.
