now it looks as if the apm bios really is broken, not a simple
hi/lo swap as in several other vaios.

this is a phoenix bios, code R0211U0.
it claims to be an apm bios 1.2.

the APM BIOS call "get power status" for all devices reports that there
is no battery installed, and "get power status" for device 0x8000 or 0x8001
(battery) returns an error which is reported as "power status not available".
so the apm bios is convinced that there is no battery at all.

i don't have too much experience with the power management system,
but i guess this means that only acpi will work here, which at current

any suggestions?
