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
[44149.624000] pccard: card ejected from slot 0
