For starters just "qemu-system-arm -M n810" is better than nothing, this 
does at least make sure it doesn't blow up somewhere when creating the 
device tree.

Booting an image and operating some usb device is even better.  Are n810 
images are freely available for download somewhere?  Failing that, is it 
possible to just install some linux distro (say debian) on the virtual 
n810 or another arm device which has a musb controller?
