I'm quite amazed that I have 50% of the processor busy with

From your dmesg:

irq3 is shared by fxp, em, bge, uhci, ehci. Quite a lot of interrupt
service routines to run, each time your NICs interrupt. I think APIC
will help, so first try bsd.mp. If bsd.mp from 3.8 isn't working for
you, try -current.
Google found this,
<http://www.microsoft.com/whdc/system/sysperf/IO-APIC.mspx>, which
explains some things.
Should I expect the same result with the sk cards ?
I don't know, I expect a bit better, but broadly similar.. I think you
should try to get interrupts allocated more sensibly first.
