This  is  trivial  to  fix  -  just  add  the  missing  EXPORT_SYMBOL
statements  to  arch/ppc/kernel/ppc_ksyms.c  ;  but be aware that the
current implementation will leak CPM resources upon module  unload  -
which  is probably the main reason that these symbols are not expoted
for use in modules.

Don't re-invent the wheel. There is an implementation  of  this  code
available  in  our  kernel  source tree (linux-2.4 module in our CVS)
which for example provides both m8xx_cpm_dpalloc / m8xx_cpm_dpfree

I sent the patches to Tom Rini. Several times. I don't know why  they
never  made  it into the official kernel source tree. [This is why we
have to maintain our own source tree.]
