oops eject cardbus 2.6.7

[Michael Dreher]

Hello,

when ejecting a cardbus card, I got the following oops.
The box is a vaio C1 picturebook, the card is part of a 
CD-ROM drive. Kernel is 2.6.7.

Just ask if you need more information.

Known problem - IDE likes to mess about with resources behind the back
of PCMCIA, and with some of the changes which went into 2.6.7, this is
no longer feasible.

However, if I can get enough of my current patch queue merged, then this
problem resolves itself, since we loose the need for IDE to mess with
the resource subsystem.
