Real system requirements for the UR22?

The system requirements for the UR22 state that it needs a dual core CPU. I’ve looked at the system requirements of other interfaces and they have tended to be much lower; so I was wondering whether this requirement was for the included Cubase rather than the UR22 interface itself.

I have an older laptop, intel M processor 1.8ghz, which was running my previous interface (edirol ua-1ex) and Ableton 7 etc. and I don’t need to use Cubase; I’ll probably do most recordings at 44.1khz. Might it not work with my computer fine? Does anyone know if the UR22s driver require a dual core processor for its basic functions?
