[HELP NEEDED] PowerPC and ICE BDM

Hi,

I'am working with a MPC855T PowerPC microprocessor and i try to debug
my soft using ICE/BDM.
My application raises a "Software Emulation" exception that is catched
by emulator and i would like to know which software instruction raised
this exception but SRR0 register is 0 (zero).
This register should contain the last instruction before exception ?
should it not ?

Is it possible to get others informations after an exception ?
Information like "call stack frames" ?

thank you for your help
Gil

I know this will likely not reach the original author but hopefully someone will see this and know something about it..
 To the OP: did you ever find answers?
 To anyone/everyone who sees this: I have an avocent cyclades alterpath ACS8 ((ATP0120-001) the processor is of course the venerable MPC855T and it has test points clearly labeled BDM but I haven't been able to find any information as to connecting to this interface with the end goal being installation of a different linux kernel/distro or at least learning what I can in the process. If anyone has any information please let me know.
