Best thing to do is keep an old 10mbit switch or hub around with 100mbit or gigabit uplink. Second best thing is to have a router that will talk 10mbit half duplex.
I've also found some poorly behaved stuff that won't autonegotiate duplex even with older switches, like my 3Com SuperStack II. Asante SCSI Ethernet adapters come to mind. Had to set the duplex manually on the switch. Along those lines, 10gig copper interfaces often don't want to talk to 100mbit ports! Found that out when we had a switch fail and stuck an older 10/100 switch in just to get back up and running.
