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.
