Current PID in static kernel memory

On a 2.4.22 kernel running on an 8xx CPU, I'm trying to find useful 
static kernel memory locations that will help diagnose problems after a 
crash has occured.

So far I have identified load averages, uptime, active & inactive memory 
and interrupt counts and I can dump these out from the bootloader.

What I'd really like is the pid of the current task but I can't find it 
as the current task structure pointer is held in a register (r2) and 
hence is not available after a reset.

Any clues as to where I could find this information?
