SysRq-T should work on PPC. It's mostly generic code. What's wrong with it?

The profile _may_ help but it's most likely to tell us that the CPU spend
most time sleeping, without actually telling us _where_ each process was
sleeping.

I'd care more if you could reproduce it with something a little more 
recent. I'm assuming you're using v1.100 of cfi_cmdset_0001.c, since you 
committed that change.
