	You will need a special HW in any case.
	AFAIK, there are the following opportunities:
1. Wiggler from Macraigor Inc.
	Seems to be the most debugged HW interface. Price - $150. Has good
"official" support in GDB under Cygwin (the patches you mentioned). Doesn't
have today direct access from Linux. There is very close to be working
'rproxy' server from QQI, which employs additional intermediate computer to
run wigglers SW under Win98/NT and allows cross debugging from Linux.
2. HMI BDM interface. Price - about $1000. There are somewhere  in the net
(or even supplied by HMI) patches to GDB to work with it. It is also said
to be stable.
3. Several other options exist (as, for example, S.Drazhnikov's gdb patch
with simple HW), but I cann't recommend them because I wasn't able to pass
simple tests.

Good luck.
