} Thats really the only place for such a routine. What needs to happen is

Unfortunately the GENERIC kernel doesn't have a driver that could claim
the ET card. Also ex_isa_identify() is called before the legacy ISA
probes are done.
IMHO, the best way to fix this would be for the dual-mode PnP/legacy
drivers to identify any cards in PnP mode, then do legacy ISA probes
using the old hard-wired port numbers, where legacy ISA probes can
be controlled by userconfig. This is really ugly, but then we all
agree that ISA sucks.
