That's a "postinstall" template thing.  "grubby" is in /sbin and is used
by RPM to bugger the boot config file (grub, lilo or elilo, see
"man grubby").  Since you installed an older RPM, it's having a problem.
This means you'll need to manually edit your boot config file.

However, if you check /boot, I think you'll find the "new old" (or
should that be "old new"?) kernel is there now.
