Also note that I am using a Compal DSDT.  You guys probably have Toshiba
DSDT's.  My native DSDT correctly reports battery status.  (although
when plugged in with a full battery it says 'charging state: unknown')
But discharge reporting works fine.

Once upon a time I was able to keep my computer up and running for over
a week by using acpi=noacpi on the kernel's command line.  This was
sometime in July (probably with the July ACPI code).  I have tried it
since then and been unable to reproduce this behavior.  (I unwisely
nuked that kernel)

However, as my computer normally stays up for ~1 day on average
(sometimes two), I could believe a statistical fluctuation that stayed
up for a week.  ;)
