Hello.
For the purpose of minimizing power consumption on a ThinkPad 600 laptop I would like to be able to issue "set power state" and "get power state" commands to the APM BIOS so as to power down the serial port and other subsystems. However the apm code does not presently support this. I have submitted a patch request to the apm code maintainer; my message (#76) can be found at: http://linuxcare.com.au/local-cgi-bin/apm?findid=76
Is this the right way to go about things?
If it is a badi idea to add this sort of functionality to the apm driver then an alternative would be to export the address of the APM BIOS so that I could call it myself from a kernel module.
