The 16650 and 16750 UARTs are backwards compatible with the 16550, although they also have some extra features that are best supported when the driver is written to take advantage of them. I have a card from Byte Runner (http://www.byterunner.com) with a pair of 16650s, and a high speed oscillator. I used it for a while to run my 3Com Impact IQ ISDN box at 230400 bps. It worked great with both Win95 and FreeBSD, and the card was only $40 or so. (I'm not using it now because my current employer bought an Ascend Pipeline for me.)
