If you can get a time stamp facility and add funtion exit as well as entry tags (or do stack hacking like I did with -Gh's __peneter() calls in MSVC), then you can do kernel block profiling. Sounds like block profiling is what you need -- not statistical profiling, which is what the gprof stuff provides. There's a paper on ftp.sage.usenix.org on profiling this way.
