16550's are useless (no better than 16450's).
What you need are 16550A's.
Semantic nit-picking... I'm sure he was using the term ``16550'' in
the general sense to imply any 16550-type chip.
I've never seen this on NetBSD (but I certainly haven't tried every
16550 chip). You might look at the NetBSD com.c driver and see what
it does.
