    Ok, the problem with boot hangs when AC is not connected to a laptop
    should now be fixed in the source tree.

    The problem turned out to be an early interrupt from ACPI caused ACPI
    to try to call tsleep() with a timeout in the SWI task code before
    the system clocks had been initialized, resulting in an infinite timeout.

    The original code misused SWI's terribly and the code FreeBSD-5 is using
    was not much better, so I rewrote the callback subsystem.


Works, for met too!
I noticed the following behaviors:
The message "Performance set to economy" is no longer visible at boot (which IMHO is favorable).
The laptop is off line noticeable slower then on line but the throttle_state's are the same (hw.acpi.cpu.throttle_max: 8, hw.acpi.cpu.throttle_state: 8) plugging the power cord in doesn't make the laptop faster, when once booted off line.
I seem to fail to discover which sysctl to tweak to get it at full speed.

Thanks you (and all the other contributers offcourse) for the excellent work, I really appreciate it!
