Battery Oops - more information

A little bit more research yeilds, that it is only when the battery is 
in when the oops occurs.

System is

	Dell i8200/BIOS A7/two batteries/Debian/2.4.20 - from debian

Modprobe works.

	# modprobe battery
	ACPI: Battery Slot [BAT0] (battery absent)
	ACPI: Battery Slot [BAT1] (battery absent)

So that worked.

Lots more below, so I will finish the body of the email here.  I have 
attached my dsdt (since that seems to be the norm).  If there is 
anything else that I can do, give me an email.
