I suspected you weren't going to be heart-broken over a slight memory performance hit, or you would have said something rather dumb like "I wan't to use my PC133 SDRAM but I want memory performance comparable to Dual Channel Ultra-OCZ Golden Sample PC3200 with Heat Spreader."
One might have believed it reasonable to infer from the very fact you want to recycle some PC133 SDRAM that you'd rather not spend as much or more on new RAM as you would the motherboard. That kind of thing just blows straight over some people's heads, for reasons I'll never figure out.
You could just as well have asked about "sound economical transportation" for your teenage daughter and without fail someone will offer something along the lines of "Anything less than a 2004 BMW M3 is obsolete and undriveable." There's one in every crowd.
If you want a fairly "modern" chipset, try the SIS651 board. Granted, things like six integrated USB2.0 ports, ATA133, 6 Channel Audio, 10/100Mbps LAN, PC2700 DDR, MuTIOL 533MB/s interconnect, and support for all 533FSB Intel processors with Hyper Threading are like prehistoric 2003 technology.
