For me the patch seems to work.
The system boots correctly and is now working for hours.

But unfortunately it doesn't make any changes to my problem.

So, okay. The big problem is that my two isdn-cards are only working in
dom-0.
When I hide them from dom-0 and create a driver-domain the drivers load
correctly
but the cards are not working.

In dom-0 my testapplication (which just calls a telephone) works and a
phone is ringing.
when starting in the driver-domain, the programm starts, no phone is
ringing and after a few seconds
a timeout ends the app.

I think it might be an irq-related problem. I found that all my
pci-devices share irq 5 and 11
under xen and that there I only have 15 IRQs (see 1st post). Starting
Linux natively there are
much more IRQ used. So I thought it might have something to do with
apic-initialisation.
Even after applying your patch I only see the first 15 IRQs.

I can supply you with debug-information if you like/need.
