after playing a bit more with xenpaging, its not working for me.

Whats your environment?

I have a plain SLES11 SP1 x86_64 installation on a Xeon X5550 box.
The client is also a plain SLES11 SP1 x86_64.
Once I boot the client and start xenpaging with 256mb, the client gets
lots of SIGBUS or SIGSEGV.
Xen prints 'Iomem mapping not permitted ffffffffff (domain 1)' in
