Where can I find the description of the the stack frame passed to a sigaction handler by the OS?

It's nowhere documented (nor guaranteed to remain compatible among different versions). There's however some sample code which never was updated for i386 as part of the MoreIsBetter sample: http://developer.apple.com/samplecode/MoreIsBetter/listing83.html

These people did update it for i386 and did some other fixes (and got ahold of a newer version somehow): http://boinc.berkeley.edu/trac/browser/trunk/boinc/lib/MoreBacktrace.c?rev=12151

The latter code is LGPL though, so depending on your licensing requirements you may or may not want to look at it.
