Interesting that you mention the 3c5x9cfg utility!  I was using this the
other night and found some strange behavior which may or may not be of
use to you.

If you change the transceiver type (? -this is from memory) or at least
enter the option for TP vs AUI, when you exit there will be another
option at the bottom of the list.  It showed as being a toggle for full
or half duplex.  As these cards have always been half duplex, I was
overjoyed(!) at this development and tried this option.  But, when I
changed this toggle the option switched from 'duplex' to 'plug and
play'!!  I have no idea whether it actually does anything useful, but
there you go.

Has anyone seen a method (or know if the card supports it) to allow full
duplex operation on the 509's?
