The module takes a debug parameter which can be used to selectively
enable various classes of debugging output, for example:
- modprobe ibm_acpi debug=0xffff
+ modprobe thinkpad_acpi debug=0xffff
will enable all debugging output classes. It takes a bitmask, so
to enable more than one output class, just add their values.
