;) kind-of : European, originating from the Netherlands, that's what
I start my presentations with right now (excusing my
approximate french ..)

with or without APIC i got all devices at shared IRQ 5; 
that choke the xl driver (workaround : disabling 905B features)
and gave me some minor problems with the ahc/sym driver (SCB
timeout and then system locked for some 30 seconds).
Assigning irq 10 to one an 11 to the other : like a charm.

beyond my competences, anyway, a A7N266 does not allow me to

no hard feelings, I like foot (and Grolsch (tiens, long time since
I didn't see that word on a freebsd mailing list ;) )

I bought a A7V8X for 69E (vat included) in France; against all expectations
rock-stable and rapid  with a couple of months old -current
(though I do not have an A7[^V]8.* to compare with for
scientific computations)
