Omnibook XE3 and apm

[James Roper]

Currently, apm isn't able to detect the battery on an Omnibook XE3. Does anyone know if:

1) There are any modules that can
2) There are any people that are or are interested in developing a module that can
3) Where I would go to find out more information
4) How I could write/modify a module that can.

I can program in C, but I have no idea how to talk directly to hardware, maybe reading the kernel source for apm would help, but how would I find out how to talk to the bios in the Omnibook XE3? I assume that's where the battery status information is found.

The trouble is not in APM, but in Omnibook BIOS, read this thread (and the answers) about that :
http://www.ussg.iu.edu/hypermail/linux/kernel/0206.3/0389.html
XE3 BIOS much likely doesn't support APM. But there is a waya activating ACPI instead : read
http://www.redhat.com/archives/redhat-list/2003-April/msg03428.html
ACPI enabling howto :

(It's for rh8.0, but process is the same on other versions, except real old versions).
