Ops, compiling 2.3.42 with athlon and without SMP-support (with dummy
APIC or what ever ) gives very poor ratings in nbench. Only difference is
CONFIG_SMP=n(and yes to the APIC support for uniprosessors) in the first
test and CONFIG_SMP=y in the latter.
Or maybe this was just bad luck and kernel compiled wrong? But would
wronly compiled kernel boot and otherwise ok?
The values seem to be roughly 1/2 wrong.
This is 675Mzh Athlon and 2.3.42 without SMP.

And this is the same thing with SMP turned on.

Oh, and you still need the following patch to compile 2.3.42 with athlon
support and SMP.
