Thanks again.

But I think there are currently no real devices available you can buy
with pacifica-support.

So I think I will have to compare opterons without pacifica support to
intel cpus with vanderpool-support, because I can currently buy such
cpus.

So how can those cpus be compared, if I need a system with 4 gb of ram?
Giving more than 2 GB to a single userspace process on an 32 bit system
can be quite difficult. Does an opteron cpu run fine with xen 3.0 in 64
bit mode, with some 32 bit guests, without any hardware accelleration?
