hostap_cs: RequestIRQ

[Shane Delight]

I've been having a problem with the hostap driver since I upgraded to
to a 2.6 kernel from 2.4.23.  Currently I'm running 2.6.10, Gentoo.  I
am using a SMC2532W-B EliteConnect Wireless Adapter to run an internal
wireless AP with the hostap drivers.  This worked great under the 2.4
kernel but I've had nothing but problems since I upgraded to the 2.6
kernel.
I used to use an ISA to PCMCIA converter which is not recognized at
all under the 2.6 kernel.  I installed a PCI to PCMCIA converter, one
made a Ricoh, and it is recognized but I cannot get it to load the
hostap driver.  It works fine with an orinoco card or a 3com ethernet
card, the only other PCMCIA cards I have avalible for testing.  Posted
below are the output of dmesg, the logs generated when restarting the
pcmcia service and the contents of the /proc/interrupts file.  Similar
messages are generated when ejecting and reinserting the card.  I've
done searching on the gentoo forums, googled it in as many ways as I
could think of and searched through both this mailing list as well as
the pcmcia lists to try and find a resolution to this.  On google I
was able to find many posts about this problem but no clear
resolution.  Hopefully someone here has knowledge about this problem
and a fix for it.
