Ok, what do I do now?

When I did an "install everything" on the Beast this afternoon, I selected the 2.2.18 kernel. SuSE, on the other hand, decided on it's own that what I really needed was the 2.4.0 sources! So that's what I've got installed. I ran YaST and told it to install lx_sus22 source files. I get a response message saying that such an action is not wise. My thought is to go ahead and ignore this message and install the 2.2.18 sources anyway. But, having ran into unannounced brick walls before, I am wondering what land mines I might be stepping on if I do this? Should I uninstall the 2.4 sources first? JLK
