While I don't believe it is officially supported (ie. not a tested 
config), I have had a dedicated MBE running with no cards on it. I then 
had a separate slave backend with a PVR-500 registering into the MBE. 
This was my config up to 0.21-fixes. It worked flawlessly for years.

I needed to do this at the time since my MBE is in a VM guest but I had 
only a PCI card at the time. The slave was actually on the host of the 
VM. As of 0.22 I moved to HD-PVRs which can now access the VM guest via 
USB. So I can't confirm 0.22 will work as well.
