Interesting. Konrad, do you remember that one of my DVB cards did 
consume double CPU time 
as compared to a) old Xenified 2.6.18 b) Xenified 2.6.34 and c) mem=2G 
Dom0? Maybe these
observations are somehow connected.

It did work, though... Unfortunately, I sold these cards to have only 
one, which is 

Carsten.

A coconut for the gentleman!

Working in dom0 and (with page-alignment of the PCI BARs) in the domU,
I did check a couple of reboots and a cold start too, just in case!

So what's to look at for the real cause?
