I think that's what most developers currently already use, aiui it's
what OE generates when you set "qemuarm" as machine name.

Not very difficult but you would also need to patch the kernel.
The openmoko qemu tree also has a 3rd party patch applied for normal
usb networking (i.e. the NIC is a usb device), which would seem to be
the ideal solution except it's buggy on 64bit hosts :( more
