don't know much about the D-Link stuff. i'm pretty much a hardcore cisco guy
when it comes to networking hardware. (well, not entirely, but definitely in
it sounds to me like you are going to have to bite the bullet and force your
switch to get it to talk to the LX.

i've got a cheap POS LinkSys dual-speed switch. it correctly identifies and
sets the ports for:
PC (Xircom RealPort CardBus 10/100) 100/full
a wide variaety of 10/half tranceivers.
no problems at all.

in my experience, it's really b0rken, and the "real" fix is to meddle with
the switches port setting. sucks, but it's life.
