David:
Firstly, great work!
There is only problem I've encountered. After applying your patch, if I do a 'cat /proc/cm/devices', I get this oops:

This only happens on our PNP-BIOS Pentiums. I have no problems catting this "file" on a circa 1994 486 box with no PNP extensions.
I have included configuration information that may be relevant below. If you need more information or would like a guinea pig for testing potential fixes, please feel free to contact me.
