The boot console?  Probably not.  Logging in to a booted system should 
work.

I actually just got a PL2303 USB-to-serial adapter:

http://www.newegg.com/product/product.asp?item=N82E16812149115

It shows up when the uplcom module is loaded.  ucom creates /dev/cuaU0, 
which could be entered in /etc/ttys.

(Rule #1 of serial: no matter how many cables and adapters you have, 
none will be correct and you will eventually have to buy or build one. 
That's why I haven't tested this yet.)
