acerhdf: add new BIOS versions
Browse files Browse the repository at this point in the history 
Added new BIOS versions for following netbooks: Acer 1410, Gateway LT31,
Packard Bell DOA150.  As the Gateway LT31 machines have different register
values for setting and checking the off-state, the "cmd_off" variable has
been splitted up to "cmd_off" and "chk_off".
