KSE does not appear to work when I run FreeBSD 6.2 on VMware

I have an amd64 machine, but I'm using a generic FreeBSD kernel.
My host OS is Ubuntu i386 (not amd64), so I'm not sure what is exported to the guest.

My physical machine is a P4 however.
Would that make a difference? (Considering my kernel/libc is compiled for a generic i386/i686).

He's not using libkse but writing his own concurrancy app by using the 
primatives.

My question is whether he is on  amd64 or i386
