I'm not really familiar with the switches, but the model 18 and model 23 cards 
are mixed over the switches and i don't think that exactly the ports for the 
model 23 cards are forced to full duplex. Further, the results are independent 
of the used switch and the used port.
netgear writes: "Automatic speed and full/half-duplex sensing
The switch supports n-way auto negotiation, and each port automatically senses 
and operates at the proper speed and duplex mode, taking the burden of 
configuration off the user."

I tried, no changes. Neither instantly (-r) nor after a minute (-v)

# mii-diag -R
Using the default interface 'eth0'.
Resetting the transceiver...
Basic registers of MII PHY #24:  3000 780d 0040 6176 05e1 0000 0000 0000.
 Basic mode control register 0x3000: Auto-negotiation enabled.
 You have link beat, and everything is working OK.
 Your link partner does not do autonegotiation, and this transceiver type
  does not report the sensed link speed.
   End of basic transceiver information.

Strange, I agree :-(
