One last point - I suggested you back up your custom config files (like 
CHERRY), but make sure that CHERRY is a version 2.0.3 (or whatever version 
of the sources you got) config file, and not a -currunt config file. If you 
are not sure, after you download fresh kernel sources, create a new CHERRY 
config file from one of the config files that came with those fresh kernel 
sources you downloade, and use that one rather than your current version of 
CHERRY.

Also, I would highly recommend you delete everyting you got using cvs update 
under /usr/src without a '-r tag' option, since those sources are for 
-current. Those sources will certainly be broken because you did not 
download the entire source tree at once. Also, you have indicated you want 
to use a stable version, not -current, so those are not the sources you 
want.

For other reading, try this link. It gives lots of hints about building the 
sytem using either cvs or downloading tarballs via cvs:
