I've tried it on Cobalt Qube 2700 and the Century LCD-8000U,
http://www.century.co.jp/products/pc/monitor/lcd-8000u.html
and it just works on ttyE0 (the LCD wsdisplay + ukbd) terminal.
Very cool!

I've also put some files and patches for trial on NetBSD/cobalt 5.0.1:

BTW, which major numbers for wscons devices on each port?
Maybe we can reserve device majors for such "serial only" ports
before importing udl(4) driver itself.
