Netgear RP614 router's that support 10mb are:
version 1 -
no (10Mbps half duplex only)
version 2 -
yes (10/100Mbps auto-sensing)
version 3 -
yes (10/100Mbps auto-sensing)

If you were to buy one in the shops now, it will probably be a v3 (white), as they have been on the shelves for over a year now.
I find these to be very good routers, I had my v1 switched on 24/7 for nearly 3 years, and it never missed a beat.
