[Problems with PCMCIA adapter and CF card on ThinkPad T60p.]

> Does irqpoll help?

Yes!

Booting with the irqpoll boot option results in correct behaviour even
with repeated insertions and removals (with or without unmounting from
desktop) and when booting with or without the adapter and card inserted.
Much better (but slower).

Booting without the irqpoll boot option and no adapter and card in at
boot results in the bad behaviour when the adapter and card are first
inserted.  Booting without the irqpoll boot option and the adapter and
card in at boot results in more-or-less correct behaviour (there is an
extra icon on the desktop for the media, but this is a known problem and
probably not related), although in the past the behaviour in this
situation has been somewhat non-deterministic.

Problem solved?  Or not?
