I finally got a chance to test, and 2.6.18-rc1-mm2 does fix my PCMCIA.
Thanks!

Thanks.  I think that patch has propagated into Dominik's git tree.

Dominik, do you intend to merge that for 2.6.18?

FWIW, I have a BUG on ejecting the PCMCIA CF card, followed by a NULL
pointer dereference.

The sequence was

boot 2.6.18-rc1-mm2
swsusp-to-disk, resume
insert PCMCIA/CF adapter
mount FS, read data, unmount FS
eject PCMCIA/CF adapter using eject button

resulting in
