Good to see you working on this! Can you explain the "It seems that the region 
is reserved for pnp", a bit more?

Are you talking about the IO-address used by the sensors logical device of the 
super/io chip, or about ... ?

Does your driver need to enable the sensors part on those MSI mobo's? Then 
maybe it also needs to search for a free io-space and program that into to 
superio config registers for the sensors logical device, before enabling it.

If its already enabled, maybe its memory-mapped instead of io-mapped, some 
super-io devices support this. Or maybe even, its mapped to the smbus instead?
