I've seen these boards myself, and they could be upgraded if you had some
of the dual 16550 uarts in the QFP package, and had the tools and patience
to replace them. Since 16550 cards are so plentiful, it just isn't worth
the trouble IMHO. For dual 16450/16550 uarts in a PLCC package, those are
not too much trouble to replace even if soldered directly to the board.
There is usually room for a PLCC socket too.
