When I boot a current kernel (on a desktop machine,
Phoenix BIOS) I get the following:

[...]
apm0 at mainbus0: Power Management spec V1.1
APM power mgmt engage (device 1)
:power management disabled (1)
apm0: battery life expectancy 100%
apm0: A/C state: on
apm0: battery charge state: no battery
apm0: estimated 0:00 minutes
APM get event:power management disabled (1)
[...]

and every second again:
APM get event:power management disabled (1)

What's going wrong? The power management options in the
BIOS are enabled (Win95 did at least switch off the power
after shutdown).

I tried a call to
apm_powmgt_enable(1);
(which is #ifdef'd out in the current driver)

This gives:
APM power management enable <apmbios enable>:unrecognized device ID (9)

any hints?
