Well, if there is no graphics card (as you told Qemu), there is no wscons
console and the /dev/ttyE* devices are not available.

You need to set wscons=NO (for rc.d to not try configuring the ttyE* virtual
consoles) and also mark all ttyE* lines in /etc/ttys as "off" (to avoid a
getty on the non existent virtual console).

In real PCs this ~never happens, so there is not automatic for this case,
but it is an easy one-time configuration change.
