powerpc disassembler

[Daniele Scollo]

Hi, my name is Daniele Scollo, and I'm a young Italian engineer.
Would you mind helping me about a PPC issue?
I use powerpc-linux-objdump to get asm instructions to make statistics 
with -d option but the asm-obj file are generated with -m7455 
architecture and maltivect. When I use the disassembler I can't use 
the -m7455 option because this architecture is not recognized?Why? if 
I use the disassembler without this option I have some new strange 
instructions (like mfdbsr, mfl2cr,
mtsprg7) not included into the 7455 instruction set.And I have some 
problems because a don't know of to disassembly for my architecture...

My system is Ubuntu 6.06.
Thank you for your help till from now. It's very kind of you to help 
me!
