PCMCIA driver resource allocation

[Bjorn Helgaas <bjorn.helgaas@hp.com>]

Question 1: Does the linux-pcmcia list still exist?  It's in MAINTAINERS:

  PCMCIA SUBSYSTEM
  P:      Linux PCMCIA Team
  L:      linux-pcmcia@lists.infradead.org
  L:      http://lists.infradead.org/mailman/listinfo/linux-pcmcia
  T:      git kernel.org:/pub/scm/linux/kernel/git/brodo/pcmcia-2.6.git
  S:      Maintained

but the archive: http://lists.infradead.org/mailman/listinfo/linux-pcmcia
seems dead.

Question 2: Documentation/pcmcia/driver-changes.txt says drivers should
now claim their own resources:

  * Resource management. (as of 2.6.8)
     Although the PCMCIA subsystem will allocate resources for cards,
     it no longer marks these resources busy. This means that driver
     authors are now responsible for claiming your resources as per
     other drivers in Linux.

But I don't see any drivers that do that.  It looks like there should
be a bunch of changes like the one below.  Is there a reason these
changes didn't happen, other than just lack of interest?
