Oh, crud! I forgot to mention: be very careful when initially unpacking 
your Linux kernel source tarball! Do *not* unpack it into /usr/src; it will 
almost certainly wipe out your current-kernel source tree (which, again, 
may not have any immediate effect on your machine, but you might want that 
source tree later...)
