You don't mention it, but you should always do a "make dep" after 
menuconfig.

I just checked here and a build with those options disabled completed 
just fine...

tomorrow I'll make sure the CVS is up to date with my local tree (I'm 
pretty sure it is) - in the meantime may I suggest you do "make clean" 
and "make dep" again, before rebuilding the kernel?

Also try re-enabling those options, just for a test, and again do make 
dep, then make.

That should be quite possible, as long as you have some reasonable 
external memory resources.

Let us know how you go.
