Yes, I had tried that but all I got was the following message on my
console during bootup:

isapnp: Scanning for PnP cards...
isapnp: No Plug & Play device found

I did notice that on my Redhat 7.1 host machine I have a
/usr/lib/modules/modules.isapnpmap file that I lack the equivalent for
on my target powerpc machine.  The file is a listing of
vendor/device/function ids.  Perhaps this may be important for the
CONFIG_ISAPNP functionality?  Any suggestions or pointers welcome !

Anyways, thanks for the suggestion.  I guess I need to go educate
myself on the PnP protocol a bit more.

Regards,
Jeff
