Won't more registers and bigger registers make task swapping slowwer ?
So it would be interesting to see a few RT-Linux benchmarks on it
thats for sure. More interesting things would be if it got the
APIC enabled , and lnot disabled like on Athlons and non SMP Pentium *
systems.

Thats a known redhat "anhancement". There is a bug in that kernel that
crashes
it when used on a athlon, i beleive it was something with the CPU
capabilities
flags, an update from the boot disks should do.
