I just booted my laptop in FreeBSD mode:
FreeBSD tamagotchi.whacky.net 5.2-CURRENT FreeBSD 5.2-CURRENT #10: Tue Jun  8 18
:03:04 CEST 2004     root at tamagotchi.whacky.net:/usr/obj/usr/src/sys/GENERIC  i3
86

I am using a GENERIC kernel stripped of the whitness options. The CFcard is recognized and works (currently with an empty 32mb card):

pccard1: Allocation failed for cfe 0
ata2: <SanDisk SDP> at port 0x140-0x14f irq 9 function 0 config 1 on pccard1

No problems with any interrupt storms whatsoever. Let me know if I can help pinpoint anything somehow.

I guess try updating your tree and building a new kernel, simply because my kernel is somewhat newer then yours and there has been quite some acpi commits lately.
