wireless pcmcia net card failure, 2.6.0-test2 -> 2.6.0-test3

[Robert P. J. Day]

  in moving up from 2.6.0-test2-bk5 to 2.6.0-test3, my linksys WCF11
wireless PCMCIA card is no longer getting activated via DHCP from the 
house router.

  from /var/log/messages, the "hermes" and "orinoco" modules are
being loaded, but then i get

  orinoco_cs: Request IRQ: Unsupported mode.
  cardmgr[...]: get dev info on socket 1 failed: Resource temporarily 
unavailable.

  doing the basic "ifup eth0" and "service network restart" doesn't solve
anything.  as i've moved from BK fix to BK fix for the kernel, i've never
had to mess with the wireless configuration.  but, clearly, something's
changed in going to 2.6.0-test3.

  "cardctl ident" sees the card correctly, so i'm open to troubleshooting
suggestions.  one of these days, i should really go through the wireless 
config docs thoroughly.
