I had similar problems on my Dell i8100 with the PCMCIA stuff in the
installed kernel (2.4.16).  I installed the "pcmcia-cs" & "pcmcia-source"
packages, rebuilt the kernel (for other reasons), & the PCMCIA stuff worked.
I don't know what the previous PCMCIA stuff was doing, but it was definitely
causing trouble.

Also, check out the following for some useful information:

I ended up disabling APIC (not ACPI, but close enough to be confusing):
	CONFIG_X86_UP_APIC is not set
	CONFIG_X86_UP_IOAPIC is not set
So, now "shutdown -h" works, pushing the power button works, & the system no
longer crashes when pulling the AC, pressing "suspend", etc.
Suspend... doesn't seem to be supported with the current acpid; it notices
the events, but isn't configured to to anything about them.  The lid
close/open is interesting, requiring at least Fn-CRT/LCD to get the screen
back, & varying based on whether I'm at an X console or not.  I don't know
where to go from here, but my system is stable for the moment.
