I tried to install PAPI 4.1.1 on my Pentium M computer (Dothan: family 6, model 13) and the configure script does not recognize it. Indeed, looking at line 4268 of the script, where the checks for GenuineIntel processors begin, there's no check for this specific combination of family and model.
The currently supported page lists Pentium M, so what gives? I tried forcing --with-CPU=p3, but ctests/zero fails. If I omit this flag, the tests don't get built at all because the CPU is unknown.
I tried this on Linux kernel 2.6.26 patched with the PerfCtr 2.4.1 that comes with PAPI 4.1.1 by the way, and PerfCtr runs fine.
