386BSD does recognize 16550A FIFOs; check the boot-time messages.  The
problem seems to be in the distributed "com.c".  A stopgap solution is
to bring your DTE transmission rate as far down as you can afford
(this will reduce the problem, but may not entirely solve it).  Once
you're ready to reconfigure your kernel, install the experimental
"com.c" at agate.berkeley.edu.  It seems to fix a lot of the problems.

Check out /etc/rc.  It has escape sequences that change the color at
boot time.  You should be able to fiddle with them and put something
in /etc/rc.local.

386BSD uses a "pc3" terminal type (check out the termcap file for more
info).  If you want ANSI/vt100 emulation, use "screen" once you've
logged on.  Be warned that "screen" has a known bug (get the Unofficial
Buglist for more info), and that ANSI emulation tends to be more
successful than vt100 emulation (at least with the shipped "com.c").
