Just for the record: I haven't forgotten this. The general problem here is
that building the ACPICA debugger requires also the disassembler. Together
these add plenty of code:

     GENERIC:                        11180269
     GENERIC + ACPI_DEBUG:           11376086        + approx. 1 %

Naturally some #ifdefs could be added.

Given the amount of problems people have with ACPI, I am currently
investigating whether at least the debug output -features could be enabled
in stock GENERICs. (Unfortunately the ACPICA build system is somewhat
braindead.)
