More details and resolution.

When I tried Debian stable (with a 2.4 kernel), everything worked great
including audible "beeps" when I inserted/removed PCMCIA cards.

I upgraded to Debian testing and then unstable with the 2.6.7 kernel and
PCMCIA devices would only work if inserted prior to booting. This
matched my Fedora Core v2 experience with the latest errata kernel, or
with 2.6.7-mm.

With Debian testing/unstable using the Debian stable 2.4 kernel
everything was peachy.

I found that loading the BIOS default setting that made everything work
(minus the audible beeps). The default BIOS settings has a screen where
all IRQs are *forced* to be IRQ 11, and sure enough, cat
/proc/interrupts showed everything on 11. I had changed it to "Auto"
instead of "11" and cat /proc/interrupts showed everything spread
around. Everything seemed to work great, except PCMCIA.

Resetting my BIOS back to defaults and now PCMCIA hotplug is working.

It seems that it *should* work with interrupts not all clumped up on
IRQ 11 (and indeed, Windows does work with that config), but for now
at least, my PCMCIA slots are working.
