Do you think it is feasible to hack this distinction between minor and
major page faults into perfmon2 without to much effort? I am not much
of a kernel programmer, so sorry if it is a silly question. But if it
is possible, I could delegate the work to one of my coworkers. I am
targeting for Intel Dual Core / Xeon CPUs.

Thank you,
