Are you trying to disassemble the dlls to view the ASM, colonel?
I can hook you up with the best disassembler out there which will disassemble them for you. You'll need to be able to understand a bit of ASM to make sense of it, but I've seen some of your contributions to the ppc community so I know you have an aptitude for it if you don't already know how :) Shoot me a PM if you'd like a copy for free.
Here is an example, the msvcr80.dll found in the windows directory of the 6700 starts like this when disassembled:
