Hello,
this patch converts 3c509 driver to isa_driver and pnp_driver. The result is 
that autoloading using udev and hibernation works with ISA PnP cards. It also 
adds hibernation support for non-PnP ISA cards.

xcvr module parameter was removed as its value was not used.

Tested using 3 ISA cards in various combinations of PnP and non-PnP modes.
