The kernel normally shouldn't, but your's stumbles over it's own ARP replies: an ARP request for 192.168.10.1 is presumably answered correctly on de0, but also on de1. In turn de0 snoops the reply, and moans. The non-working autoselect might be due to different PHY chips used (jugding from the vastly different MAC addresses, I guess the cards are from two diffent vendors). Check what dmesg says about the PHY chips. Your hub/switch does support auto-negotiation, does it? Some PHYs are not very good at auto-sensing, AFAIK. In this case, set the media manually.
