Weird PCMCIA behavior

[Faux Pas III]

Note: this is the same laptop mentioned above in the Maestro 2E
thread above, so the same weird-ass power behavior applies here.

When on AC power, everything is dandy with PCMCIA.  When on 
battery power, PCMCIA device detection fails, emanating a lower
than normal pitched beep, followed by an even lower beep.
However, if the apm module is inserted, this makes it behave
properly, but ONLY if the apm module was compiled with 'Make
CPU idle calls when idle'.  Yeah, I know it's ucked fup.

Some possibly relevant details:
