building reiserFS into kernel

I'm a newbie to SuSE, but I've used RHL for years. I'm working on my first test install and it all went quite well. I now want to build a custom kernel and I'd like reiserFS support compiled in so that I don't need an initial ram disk for booting. However, I get an error when trying to compiler the kernel that some reiser_<something> symbols are undefined and a linking fails. If I change reiser to be compiled as a module, everything is just fine. I'm guessing that if reiserFS is build into the kernel, then there will need to be some other module that must be compiled in rather than made a module... Anyone have any experience with this? Thanks! -Michael
