Did it work before?

I wouldn't expect SAL 2.9 to implement a call defined in SAL 3.2,
unless I'm seriously misunderstanding something?

Annoying noise, I agree with you.

More annoying noise; I thought about removing or changing that
printk the first time around to something like KERN_INFO since
failure of that particular SAL call doesn't really affect any
functionality.

Opinions?

This looks like a Montvale? That means we *should* be getting
meaningful "physical id" information from /proc/cpuinfo. :(

What values were you getting before my workaround above?

And again, the more interesting question is, why is your SAL
reporting a revision of 2.9?

Thanks.
