True.

I made three tests: - STGT (with standard Debian Lenny kernel) - SCST with default build options (i.e. no "make debug2perf"), no kernel patches (standard Debian Lenny kernel) - SCST + "make debug2perf", with kernel patches (Debian Lenny .config + SCST patches and proper option enabled)
I'll post the results shortly.
