I recently posted a plea for help regarding X screen refresh 
problems with a Fahrenheit 1280 card (random areas of the screen
not refreshing after exposure events, text characters and cursor
becoming corrupted).  I tried an old S3 driver program which
exhibited the same effects, but then spotted a bugs report that
came with the driver.  The report said that there could be
problems with conflicts with serial port COM4.  As it happens, I'd
recently added a serial card to the system and configured COM4....

....soooo, I thought, nah, it can't be that, but I'll take the
card out anyway and see what happens.

Et voila!  The X refresh problem went away!  Re-inserted the serial
card, configured now for COM2 instead of COM4, and everything
works perfectly.

I've no idea why there should be an interaction with the COM4 port,
but the bug report was right.

So, if anyone out there maintains an FAQ on Fahrenheit cards, you
may care to add the following:

_____________________________________________________________________

Fahrenheit 1280 S3 adapter conflict with COM4.
==============================================
Problems of screen refresh under X-windows have been experienced
with this card where the system also contains a configured COM4 port
(base address 2e8, IRQ 3).  Symptoms include random areas of the
display not refreshing after exposure events, text characters
disappearing at random and/or changing to black rectangles, X
cursor changing to a set of short vertical bars.

Workaround is to reconfigure the com port to something other than
COM4.
