Are "older" CPUs unsupported by the BOINC software?
I ask because my, admittedly long in the tooth, Pentium MMX system which happily munched away on the old seti@home client has problems running the CPU benchmarks, either running the precompiled linux version (for i686 according to the filename) or by compiling it from source.
I get the following output:

System is a Pentium MMX approx 200Mhz, running debian linux, kernel 2.2.20-compact.
Incidentally and probably not relevant, the seti project source won't even compile on this machine, although I've not investigated further to narrow down the cause.
