Need help with compiling my kernel

[Andrew Konosky]

I successfully compiled and installed a custom 2.6.9 kernel a few days 
ago and have been tweaking the settings to get rid of error messages 
during boot. Right now the kernel boots normally (actually a lot faster 
than the yum rpm kernels since I took out all the extra stuff like IBM 
thinkpad support, etc...) but after recompiling twice tonight, I still 
cannot get rid of the last error message. I can't find the actual error 
message in any logs (which one would it be in? It's not in 
/var/log/boot.log)

When the system is booting, at "starting NFS4 idmapd" I get a big red [ 
FAILED ] and something to the effect of "FATAL: module sunrpc not 
found." I'm not sure what the module does, but when I boot the rpm 
kernel and do lsmod, I see that sunrpc is loaded. Where do I find this 
in the xconfig menu and what else do I need to enable?
