Can you clarify the reason for the PAE benchmarks? Are you considering
dropping the -686 flavour as well? Since PAE-enabled kernels may not
work on all currently installed -686 systems[1], I can only see this
working reliably by transitioning -686 systems to -486 images.
If that's the case, then the valuable benchmarks are:
* 486 vs. 686 kernel on 686-capable systems
* 486 vs. 686 vs. k7 on k7-capable systems.
Right? Or are you wanting to see PAE vs. non-PAE on systems with <=
4G?
[1] At least, there's a note in Kconfig that says:
'NOTE: If you say "64GB" here, then the kernel will not boot on
CPUs that don't support PAE!'
