Yes, and i hope your 3 times retry with swiotbl will also help for the observed
problems with allocating dma mem after some time.

Yes.

.config of the 3.0+ kernel attached
lspci and lsusb attached (from booting with 2.6.32.35 kernel, (since the 3.0+
kernel panics on boot), so you don't see the usb devices in the lsusb, since
pass through of the usb cards works in this case)
The pinnacle and kworld usb video capture devices (both em28xx based) should
have been passedthrough, and i'm using them for quite some time, so no they are
not new.
I do have the xen-pciback lines in grub (exactly the same as for the 2.6.32.35
kernel, except for the xen-pciback.passthrough=passthrough parameter because
with 2.6.32.35 you specify it at compile time ), but it seems no device gets
seized by pciback some how.
