I didn't write a test program [yet?] - I'm not sure how one would test
this functionality, not to mention making something that fit the eCos
"test" model.

As far as using it, there is a documentation chapter in the main user's
guide.  It's pretty simple - just call profile_on() much as you would on
any Linux/Unix system.  This will gather the profiling data, as well as
start up a TFTP server thread.  This is how you gather the profile data,
by running TFTP to your target (from a host) to capture (and reset) the
profile data.  This data can then be processed using 'gprof'

As for the 8xx - that's the only platform that this has been tested on!
