I have done (and am still doing) this -- debugging mostly ppcboot,
Linux (occasionally) and NetBSD (very occasionally ... unfortunately).

I've been using both an adapter that is supposed to be compatible with
the McCraigor Wiggler, plus with a DOS-based tool (yuck!), and Frank
Przybylski's BDM adapter along with his MPCBDM patch for gdb.

I'd love to see this driver ported to NetBSD (especially if it will
support the PPC and one of the adapters I mentioned above ;-); actually,
I've already thought about porting it myself ...

Please drop me a note if you actually start this project and need help
with the PPC and/or Frank's stuff; I'd be happy to support you.

Ceterum censeo Microsoft esse delendam.
