How about the 8250N-B's?  Are these chips any good?

I have a Bell-Technologies HUB-6 card and got it running at 19.2k
without any problems on my reasonably-performing 386 (although its
only at 20mhz).  The cips are marked INS8250N-B, and the docs
say they are "high performance 8250 chips"... Also, this card appears
to be supported in the driver.  Are there newer models with 16550A's
on them?

It's not how many mistakes you make, its how quickly you recover from them.
