There must be a reason that there is a "clarifications"
paper for each spec issued...
(...while the PnP specs are relatively well written
compared to the BIOS boot stuff.)

I guessed it. Otherwise the vendors would not get away with
their non-conforming BIOSes. I was hoping it is a minority, but
it appears now that it is a significant fraction. So we have to be
generous too.

While we are here: Does the "get APM table" call enjoy any
popularity? I was playing around with powering down individual
devices via APM and found that the PnP BIOS call which would
provide the missing link between APM logical IDs and real
devices is not supported on my boxes.
