laptop-detect returns $? == 0, so it works, provided the 'battery'
module is loaded, which I suppose is true for the installer kernel.  I
build 'battery' as a module, because I want to figure out how to swap
out the spare battery for the DVD-RAM during a hibernate cycle.  (I
think I can use fake IDE hotplug for that, but have not tried it.)

As an aside... we really need a battery recalibration / reconditioning
program for Linux.

The dmidecode output shows that the OEM did not fill out all of the
fields in the BIOS, ie, serial numbers, etc.  The chassis type is
reported as 'desktop'.

One more clue you could add to laptop-detect might be to check for a
"Mobile" processor.  I bet you can simply grep for "Version: Mobile" and
get that.  There are "desktop replacement" laptops that are not using
mobile CPU's or chipsets.  I guess that checking for a battery is the
most likely test to succeed in the most laptops.
