How would we ask cardctl to do the work?  I abhor screenscraping, plus you 
get next to zero error reporting beyond exit(n).  I would actively argue 
against opening a pipe to cardctl and reading its input.  I think my 
current approach is quite compartmentalized and doesn't really affect HAL
all that much.

I don't think plugging into /etc/pcmcia would help out out much either, 
since we already get hotplug events for net devices through the hotplug 
scripts.  Its just a case of matching up the device name (though the 
parsing part is a bit ugly, yes.  HAL does a lot of parsing already, like 
the PCI device/vendor name stuff.  I don't think PCMCIA is all that 
different in this respect).

David and I are actively working to get the PCMCIA+sysfs patch into the 
kernel ASAP, this is simply stop-gap measure until that occurs.  When that 
happens, this patch will come out and we'll just use sysfs as normal for 
PCMCIA devices.
