There are more means to check hardware revisions:
HID - Hardware ID
CID - Compatible ID
UID - Unique ID (good to distinguish instances of the same device on the
board)
_HRV - Hardware Revision (6.1.6 describes this one)
Everything is described in the spec. Does anybody care to read?
P.S. More I reading this thread more I become thinking that people screw
ACPI use in many ways...
