People at my place of work are telling me that the Vision-Ice supports "backtrace" and the BDI2000 does not. I looked on the Abatron website and it doesn't say. Can anyone confirm or deny this?
By "backtrace", I mean the ability to set a breakpoint, hit that breakpoint, and be able to see the last N instructions executed.

We, too, have used the BDI2000 in such a fashion. I agree that it can be invaluable when debugging the interaction between a userland application and a kernel driver.
Can you describe the method you use to do this? Our process is a bit cumbersome, involving putting a breakpoint in a driver's ioctl() function that will only be called by our application. Once it is hit, we use add-symbol-file to get the information for our application's binary, and we are able to proceed. This is on a PowerPC chip, with the special "BDI2000 support" hack turned-on.
Is your method any "cleaner"?
Thanks,
