Can you do

for i in /sys/bus/pnp/devices/*; do if [ "$(cat $i/id)" = PNP0b00 ];
then cat $i/resources; echo options; cat $i/options; fi; done

and provide the output? It sounds like you have the same problem I do,
that is that you have no IRQ listed in the PNP table.

Though, actually, on reading the code:

The code for checking for a platform device only gets included if
CONFIG_PNP isn't set! David, surely this should be a runtime thing
rather than a compile-time one? Right now building a kernel with PNP
support will break horribly if it's then run on a non-PNP system...
