I can't check this until Monday, but from memory:

They're intended to just work, although some command line shenanigans are 
required at the moment. I've had other virtio devices working on ARM 
vexpress-a15, can't remember whether serial did or not.

Self describing - qemu adds them to the device tree before it passes the dtb to 
the guest kernel.
