The architecture manual specifies ISA_PNP_PROBE in non pnp ISA drivers for 
that purpose.  As I understand it, John doesn't like the ugly nature of 
passing in a null device list for non-pnp ISA drivers.    Hard to argue 
with that.

So why not gin up a tiny little boolean kernel function 
'device_is_pnp(dev)) ' that does the right thing for non-pnp isa drivers - 
once -,right after wherever ISA_PNP_PROBE is defined in the kernel?
