Will look at this in more detail but as first testing feedback -- I need 
this on top.

Both ISAPnP and PnPBIOS for some or other reason set the priority to 
0x100 | prio after which that 0x100 is immediately masked of again in 
pnp_build_option() leaving just the prio. Your new scheme reserves 16 
bits for the priority though meaning the 0x100 survives causing it to be 
considered "invalid" by at least pnp_option_priority_name() for example.

There cannot be any currently valid reason for the 0x100 it seems given 
that it's immediately masked of again in pnp_build_option() so let's 
just get rid of it...
