What you want is the 'clear' command - it behaves like set, but sets the
value of the tree node to NULL. The separate 'clear' command is needed,
since the second argument to set can be any string.
So, if you do
augtool> clear /files/etc/grub.conf/title[1]/kernel/notsc
you'll get
kernel /vmlinuz-2.6.18-128.el5 ro root=LABEL=/ apm=power-off divider=10
notsc
in your grub.conf.
