the resource activation if we're dealing with our grandchild.
Otherwise, we run into two problems. One, if the pccard layer wanted
to allocate and activate something, we'd wind up trying to do the
wrong thing twice: the ivars are wrong and we don't want the bridge to
map the resource to the slot. If we're more than a grandchild, then
who knows what kind of ivar is present. In either of these cases, we
just pass it up the food chain.

the device to run with now power applied to the device. Most cards
failed to deal with this gracefully, and thus would hang on card
eject.
The power down event, for those keeping score, is what causes the
interrupt for the card.

to pccard_insert_beep() at insert or remove time which could occur
due to noise on the card-present lines.
Clean up some code in pccard_beep.c; we were depending on the order
of evaluation of function arguments, which is undefined in C. Also,
use `0' rather than `NULL' for integer values.

o Attempt to disable the slot when we detect that there are problems with
it in our ISR. This should make polling mode work better for more cards,
but more work may be needed. This "disabling" sets the card interrupt
register to 0. This worked for me for lots of tests in polling mode.

o Use a table of names rather than a big case statement.
o Cull a few of the "unused" controller types that we map to other times

o Enforce legal IRQs. You are no longer allowed to try to use IRQs that
will fail on all known ISA/PCI <-> PCMCIA bridges. The bridges do not
have pins for these illegal interrupts, and all of them are listed as
reserved and/or illegeal in the datasheets depending on which one you

o Always clear the bit that steers the management interrupt either to the

on suspend/resume and after windows boot, and it does't hurt to clear it.
NOTE: this might mean we can share this interrupt in the future.

possible to have different probe/attach semantics between the two

Compatibility methods for OLDCARD drivers. We use these routines to make
it possible to call the OLDCARD driver's probe routine in the context that
it expects. For OLDCARD these are implemented as pass throughs to the
device_{probe,attach} routines. For NEWCARD they are implemented such
such that probe becomes strictly a matching routine and attach does both
the old probe and old attach.
compat devices should use the following:
/* Device interface */
DEVMETHOD(device_probe), pccard_compat_probe),
DEVMETHOD(device_attach), pccard_compat_attach),
/* Card interface */
DEVMETHOD(card_compat_match, foo_match), /* newly written */
DEVMETHOD(card_compat_probe, foo_probe), /* old probe */
DEVMETHOD(card_compat_attach, foo_attach), /* old attach */
This will allow a single driver binary image to be used for both
OLDCARD and NEWCARD.
Drivers wishing to not retain OLDCARD compatibility needn't do this.
