With old (really old!) hardware, it's not about adding a module, it's about having a kernel that doesn't require modern hardware. Basically, there are certain hardware features that are not in your cpu (cmov commands) so you need a kernel that is older and will not be looking for it. I have not seen a kernel module that can emulate missing cpu capabilities. So you will need an _old_ real i386 kernel and that will require all the supporting libs to be compatible. Thus you'll need two chroots and a mechanism to point clients appropriately. As you know the MAC addresses, you can group them in dhcpd.conf and point them to the correct chroots that way.
