kernprof patches for ppc?

Hi guys,

I'm trying to track down a long-running code path on a UP 2.4.22 system 
running on an mcpn765 card.  It's got various vendor patches and drivers 
applied, and *something* is taking up to a second in the kernel very 
intermittantly.

Has anyone ported kernprof to ppc for 2.4?

Chris
