I just tried 16550V2 and it worked.  I wish there were a more scientific
method to it, but alas, there is not.  My hardware is a 486/120 AMD with an
USR Sportster voicemodem (external).  The serial card was an old 16450 based
ISA card that had one of it's ports upgraded to the 16550AFN chip previously
mentioned.  Running RH 6.0 out of the box.
