FWIW, 2.5.73+ booted w/ acpi_os_name='Microsoft Windows NT' does show
accurate battery and ac info on an i8100 w/ a14 bios. (they are up
to a15 for the 8100.)

My next test is .74+ with acpi_os_name='Windows 2001'.

(The two acpi_os_names come from the dsdt; the latter is what the
dsts expects for xp.)

I'm not sure whether the patches that went in to 2.5 since 2.5.70
fixed it, or whether the dsdt just works better if it gets to store
0x10 or 0x40 into MIS3.... But I suspect the patch is more important.

(Incidently, not specifying an acpi_os_name for that dsdt is the
same as specifying win98 aka acpi_os_name='Microsoft Windows'.
The 4th choice is win me.)
