This is a complete guess, but I'm curious whether it would work:

You can make links in the /dev directory to existing devices by using 
entries in /etc/devfs.conf, so in this case you could add a line like:

link	cuaa1	ttyS1

This works fine with FreeBSD native applications, so I use links like 
this for my old serial port palm base, and for a cdrom link. Whether it 
would work with Linux compatibility stuff, I don't know. But, as I said, 
I'd be interested to find out.
