Hmm...  IIRC, the NEC vr4121 CPUs have some kind of built-in power
management support.  I believe this built-in power-management only
reports something like 3 levels of power information (good, medium and
low).  Perhaps the 'good' setting is mapped to a reading of 80% or
higher...

I believe the reason you get a more accurate reading in WinCE is because
IBM has added their own enhanced battery meter (which is why it only
shows up in their utilities and not in WinCE proper).  NetBSD probably
doesn't support this.

Anyway, this may just be total speculation, but I do recall reading
something about this and thinking it was kind of weird the last time I
looked at the NEC documentation for the CPU.
