I've thought about this for a while, and all I can really offer right now
is the observation that IBM ThinkPads are Really Weird. Not very
helpful, sorry. 8(

Try 'sleep 5; zzz' - this may be a known problem with wakeup events being
delivered late.

I can intuit that there are interrupt-related issues here, but it's hard
to know what might be going on.

These are all standard devices.

This is part of the soundcard.

This is your trackpoint.

This is the IRDA port.

And I don't know what this is. I don't *think* it's the pccard/cardbus
stuff, which is the only real way I can imagine that PNPBIOS could
"rightfully" be tripping you up.
If you can narrow down the date at which the PNPBIOS option actually
started causing you problems, it might be possible to work out what is
actually going on. If you have a local CVS repository and a little time,
a binary search between a "known broken" and "known working" date should
be pretty easy.
Thanks for the feedback; sorry that I don't have any better answers for
you. 8(
