This has been one of the sore spots with me, this requirement that I 
make a new kernel, and sensors doesn't work because its referenceing 
the one that running, not the one thats building courtesy of the use 
of the uname facility to discover the version numbers.  I'd much 
rather it reached back into /usr/src/linux to discover this since 
that link *will* be valid for the kernel under construction.

ldconfig?  Something tells me I really do need to rtfm better than I 
have recently...

Which, up to and includeing 2.4.22-pre8, worked just fine.

I'll give it a shot, Jean, thanks.
