Are those calls required even if the corresponding driver is not 
compiled into the kernel? That is, would an unconfigured Yenta prevent 
the PCI bus from going to sleep?

Looks awfully familiar:

I saw a regression between 2.5.31 and 2.5.32, but couldn't pin the 
problem down any further. I haven't looked too far into the driver model 
power management code, but I don't think it's in apm.c.

Also saw your post about the 3c59x cardbus adapter. I can't recall ever 
being able to suspend the machine with that card inserted (including 
under 2.4-- I always had to eject the card before suspend or hibernate). 
Not sure if that's the exact model I have, but the name sounds similar.
