There is no special requirement for RAM to work with an AMD system at all. As long as it adheres to Intel's PC100 specification, you're fine. Depending on the quality of a PC133 stick, you may not be able to run your it at CAS2/133 MHz, but it should certainly work at less agressive timings, such as 133 MHz, CAS 3-3-3.
BTW, that price is a little high. I sell Micron PC133 128M for $90, which is considered top quality. Personally, I've used el-cheapo generic PC133 in most of my AMD builds and RAM has never been an issue.
