Patch: Pass parameters to xirc2ps_cs via kernel command line

[David Luyer]

Alan,

Looking forward to your talk tomorrow at linux.conf.au.

Here's an addition for drivers/net/pcmcia/xirc2ps_cs.c dedicated to all the
guys who were playing flood-ping-the-broadcast in the networking room
downstairs at linux.conf.au, so that I can specify lockup_hack = 1 in my fully
non-modular kernel and not have my ethernet lock up under extreme load :-)

(relative to: 2.4.0-ac9)

It occurs to me it would appear relatively trivial to write a "default" __setup
function for anything with module parameters (viz, xirc2ps_cs.lockup_hack=1).
Would a patch to that effect be likely to be accepted?

David.
