Yes, but I'm not sure if NetBSD works one those.

Why? I don't think that x86 is *that* bad. Many problems with existing
x86 system are related to PC architecture problems and legacy

Which ones? Beating a 3.2GHz Pentium IV in single chip integer performance
is a hard job. I'm not sure if any RISC chip can do that, maybe IBM's
latest Power5 CPUs.

Modern x86 CPUs are RISC chips which interpret x86 instructions.

That's not true. Optimizing code for RISC CPUs is very difficult.
Just look at the lacking performance of IA64 or UltraSPARC binaries
compiled with GCC.

Intel wants to depricate x86 because the Itanium architecture (IA64) is
covered by a lot of patents and they finally get rid off competitors like
AMD or VIA. And I believe that IA64 is going to die anyway. The performance
advantage over Xeon or Opteron system doesn't justify the price. And
thanks to AMD64 (or EMT64) the 4GB limit is no longer an issue.
