2.2.14 is prehistoric stuff. Don't waste your time on  all  the  bugs
and problems that have been fixed since.

Ummm... What's BCSR4? If PPCBoot initializes it, why do you  have  to
initialize it again?

Sic! So get PPCBoot running first.

Among all the things you don;t care to mention is which  bard  you're
working  on.  My  guess is that it simply never was really working in
that old kernel version.

As I said before: you are wasting your time. Use a current kernel.
