I have just committed Marc Horowitz's new PCMCIA framework to the trunk
of the NetBSD source tree.  NetBSD-current now supports PCMCIA.

The code supports the Intel i82365 and compatible PCMCIA bridge
chips, and the following devices:

	aic		Adaptec APA-1460 SCSI (and compatibles)

	com		modems and serial ports

	ep		3c589 and 3c562 ethernet

	ne		NE2000-compatible ethernet

	sm		Megahertz X-JACK ethernet

For details on configuring these devices, see the GENERIC kernel config

Here's example output from my NEC Versa 6030X:

Note the last two "irq" related lines... the code dynamically allocates
IRQs for network interfaces when the interfaces are brought up, and
frees them when the interface is brought down.  Don't be alarmed by
these messages :-)  The code also performs simple power management,
in that when an interface is brought down, the power is turned off to
that card, preserving battery life.  A future project is to have the
in-kernel APM code notify drivers that care that the system is going
to standby or suspend...

A round of applause for Marc, who worked hard on this.  Thanks a bunch!

Others that helped get this going once Marc had the basic framework in
place: Matt Thomas, John Kohl, Bill Sommerfeld, Enami Tsugutomo, and

If you have questions about or problems with the code, plese don't
hesitate to send an e-mail or bug report (the latter with send-pr, please :-)

Have fun!
