In further testing, -rc6 is fine while -rc6-mm2 fails.
Under 2.6.17-rc6 (after having inserted and removed the card, but that
doesn't seem to make much difference) I have

The diff between -rc6 and -rc6-mm2 shows that they have the same ioport
assignment (there's only a textual diff due to ACPI string changes).
I've put just about everything you could want to know about the two
kernels at

and
