BDM4GDB is as dead as the BDM debug interface of the PQ1 (MPC8xx)
processors.  They have been dead for nearly a decade now.

There are a number of (usually USB attached) Jtag adapters supported
for example by the OpenOCD project.

Soem of them also claim to be BDM compatible, see for example
http://www.amontec.com/pub/amt_ann003.pdf

I have never tested such a combination myself, though.

Well, of course there is and always has been the nice BDI2000 /
BDI3000 JTAG debuggers by Abatron ...  Sometimes you can get such
beasts relatively cheap on ebay... (especially Rev. B types which
don't work with more recent processors).

Best regards,
