PATCH: netpoll with xircom_cb

[Petr Konecny <pekon@fi.muni.cz>]

Hi,

I have a headless computer with xircom pcmcia card and needed netconsole
on it. After looking around in other drivers I concocted this patch.  It
survived light testing. I have no documentation for the hw, so it maybe
totally bogus. What do you think ?

                                                        Petr

lspci -v of the card is:
