FreeBSD 5.2-CURRENT on HP Omnibook 6000 - ACPI problem

I have an annoying (but relatively minor) problem with my HP Omnibook 6000 
(BIOS 1.82 - I can't update to 1.83, which is only a SpeedStep update, as my 
floppy drive is FUBAR) running FreeBSD 5.2-Current (last update at 06:47 UTC 
on the 5th of January, but it's always been the same with any 5.x version).  
It's connected via an HP docking station, to a Belkin KVM along with a few 
other systems (2 Windows XP boxes and a SunBlade 150).

The problem is that with ACPI enabled the eject button on the docking 
station doesn't work.  Disabling ACPI makes it work again.  I've disabled 
two ACPI methods:

lid: Because the lid is normally shut - I don't want the system going into 
standby all the time :>
thermal: Because sometimes a wild temperature is reported, causing a 
poweroff.  Certainly I doubt the values reported (over 200 C) when this 

However everything else is left alone.

If I can help in diagnosing what needs doing to get the eject button working 
I'm interested in helping.

On a related question - is it possible to tune the ACPI events (as you can 
under Linux)?  I'd like to keep the thermal action, but set it to poweroff 
on 2 over-temperature events rather than one.  It would also be nice to find 
some way of setting the lid action to disabled when docked.

Yeah, I know - not asking for much am I :-)
