Well, I added this instrumentation, but at the same time I also
removed "device apm" from the kernel config and added "apm_load="YES""
to loader.conf.local so that I could play with it more easily.
Rebuilt... rebooted... needless to say, it works now!
apm0: <APM BIOS> on motherboard
apm0: found APM BIOS v1.2, connected at v1.2
Does loading it as a module change the order in which apm and acpi
are probed?
It looks like I had not edited this kernel config since late 2004,
and had used it, i.e., with "device apm" included, for builds of
several 6.0 and early 6.1 kernels with apm being fine.
In the cvsup I did between 6.1-RC1 and the recent 6.1-STABLE, the
following 149 files had been updated. Maybe this will help pinpoint
where something was changed...
