Hmm, no, doesn't work. :-|  In /proc/interrupts IRQ0 gets increased, not (in
my case) IRQ 11. And also in /proc/timer_list next_event gets increased for
the pit device, not cs5535-clockevt.

But that's even without sharing enabled ... I guess I'll have to figure out
first what's going wrong here and then re-test. I'll get back to you ...

Thanks and regards,
Jens
