Err yes. I don't think I was clear enough.
With 64 bit Xen it doesn't need PAE to access all the RAM but my
question is about using a 32 bit Xen kernel (which would need PAE)
rather than a 64 bit kernel as NetBSD is not compatible with 64 bit
AMD64 kernels yet.
I can use a 32 bit kernel with PAE on my Opteron as it is capable of
running normal x86 code (presumably which also includes PAE).
