No such irq.  As a workaround, try disabling your parallel port drivers
(lpt, ppc, plip, ppi, etc.)  If things work then with ACPI enabled, we're
certain it's the parallel port irq routing.  But I'm pretty certain that's
the case.  Please send me a link to the output of
acpidump -t -d > thorsten.asl

I'll look at the _PRT entry.
