Hey, wait a minute here... These values are correct, but the kernel log says 'pmc0 not accessible'. Stefane, is this one of these strange platforms that (bogusly) reserves a PMC counter for NMI usage? The kernel log says:

I don't have code to handle this in PAPI...Darn it. I really wish that there was code to hide this from the user. Will, just for fun, try to disable your NMI and see if you get PMC0 back.
