Nonsense, binary firmware/microcode images are perfectly acceptable in
OpenBSD, so long as the redistribution terms are clearly defined and
suitable.
Take a look in /etc/firmware.
Binary-only *drivers* however are not acceptable, these would have to be
loaded into kernel space.. performing all sorts of black magic that
would complicate development.
In this case, I found a site which seems to indicate a few models
require a separate driver.. however it also indicates that later models
use a TI-based chip, perhaps it might be possible to adapt the uticom(4)
driver?

No clue.
