Please refer to src/UPDATING for -current.
The new pmtimer device is necessary for laptops. Failure to
include the device will cause suspended laptops losing time
when they resume.
Currently pmtimer won't solve the broken statclock problem...
The timer related code at suspend/resume time have been moved from APM
to pmtimer so that ACPI (includes new power management system) use
pmtimer at sleep/wakeup time as well.
Thanks
