EB01 is the version of the latest leak of 2.2, not the version of a kernel.
Search the Development forum for Voodoo. There are quite a few Voodoo kernels out there for 2.1. The ones from jt1134 are pretty popular. Also, adrynalyne has some test kernels available. I was using his Test 5 (non-voodoo) for quite a while and it was pretty stable. There are other developers with Voodoo kernels as well, so look through the search results and figure out what you like best.
The one thing to keep in mind is that some of the newer 2.1 kernels are only compatible with the latest officially released firmware (DL09). You might need to upgrade her phone (OTA) before proceeding with adding these newer 2.1 kernels.
There is a Voodoo kernel available for 2.2 currently, but you would have to upgrade everything to 2.2 (i.e. EB01). There is a thread for it by jt1134, and it's a stock 2.2 kernel with Voodoo and custom boot animation support.
