While doing a little textual cleanup on the cardbus(4) man page, I
noticed the description of the flag to the cardslot device, which when
set causes a device to be attached immediately rather than later, by
the event thread. The purpose of this seems to have been allowing the
use of card slot devices as root devices.

However, since that was written, we've added a mechanism to permit
device threads to attach devices after normal configuration but before
root device determination (It even seems to have been written with the
CardBus case in mind). Now that that's there, is the flag and
associated code still needed?

If not, I'd be happy to remove it.
