Subject: [PATCH][bisected]pcmcia:yenta_socket.c fix broken wireless cards.

I've an old dell inspiron 1200(amazingly still works), that use's
a D-Link DWL-G650, and/or a Dell Wireless 1350 for it's wireless
connection.

With using opensuse11.2(kernel:2.6.32*), the card(s) work fine, but as soon
as I pulled the latest HEAD, all hell broke loose. So after doing a
days worth of bisecting with this machine(painfully slow), it finally
came down to this commit:

commit 28ca8dd71fc170090edca62cb8129625d01b7760

    pcmcia: honor saved flags in yenta_socket's I365_CSCINT register
    
    Instead of overwriting the I365_CSCINT register, save the old value and
    merely change the bits we care about.
    
    Part 1 of a series to allow the ISA irq to be used for Cardbus devices
    if the socket's PCI irq is unusable.

so after fussing around with this commit, and yenta_socket.c
I come up with something, that does get my cards
powered up, and all good(hopefully).

Anyways please have a look, if you need me to test something
different let me know.
