Re: amdtemp module does not find any sensors on 5.99.55

Jared McNeill pointed out in a private Email:

        That's because pchb already claimed the device. You need to
        drvctl -d pchb<N> for the 'AMD64 Family XX Misc' device before
        loading the module.

This is indeed the problem.

Unfortunately, these machines seem to have lots of pchb<n> devices. 
(The machine with dual Opteron-6172 has 21 pchb's, my other machines all 
have 6.)

It seems that modularizing the amdtemp driver might not be such a good 
idea unless the driver itself can identify and detach the conflicting 
lower-priority pchb<n> attachment.

As a secondary but related question, would it not make sense for the 
amdtemp driver's modcmd(CMD_INIT) routine to fail if there were no 
devices attached?
