Massiverobot, can you post or PM the model and revision of your Ethernet board? I'm compiling a list of cards with/without auto-negotiate compatibility.
From what I've gathered, a lot of these PDS Ethernet cards use somewhat nonstandard interval/length link integrity test pulses. These pulses are closer in form to the fast link pulses used to advertise 100mbit/full-duplex capability, so a connected auto-negotiate port will configure itself to the wrong speed/duplex. The PDS Ethernet card won't be able to acknowledge the link, so the auto-negotiate port may or may not indicate a media connection. If it does, diagnostics will generally report a connection problem. These problematic cards do not work with any hub/switch/router/NIC that has 100mbit or gigabit capability, unless speed and duplex can be configured manually.
The PDS cards that work seem to be using a standard LIT (link integrity test) pulse which auto-negotiate ports automatically recognize as coming from a 10mbit half-duplex device.
