I rebooted a few times this morning, and the loss actually takes place 
between -rc5 and -rc6.  At rc6 and rc7, any attempt to load the it87 module 
gets a message advising the resources are busy and it refuses to load.

I'd get a sample of the error but I'm booted to -rc5 atm and its working.

I also noted that the output of sensors, when it works, contains more temps 
than gkrellm displays, except for THRM, the rest are all displayed as 32F in 
gkrellm.

Attached is a log of sorts, consisting of the output of uname -a, followed by 
the output of sensors during that boot, and the sensors modules loaded and 
linked during that boot.

Thank you.

And it is no longer possible to load the it87.ko module,
an lsmod says hwmon_vid and hwmon is loaded, but it87
claims the resources are busy and refuses to load.

So this is some change between -rc5 and -rc6.
