OK, I've added the parameters from JP. I'll wait until Leif supplies
us with the AMD Bobcat timings and that will probably have to do.
On the way... Some figures vary quite a lot (despite the machine being
otherwise idle), so I'm running tuneup a couple more times.
The one major thing we don't have is ARM tuning values. But we just
don't seem to have any ARMs online anywhere at the moment (except in
our pockets).
I asked Julien Puydt, and he gracefully contributed the attached ones
for ARM/Linux, GCC 4.6.? (ARM v7l, cf. attached cpuinfo).
