I think, in FC4 there is a new option in grub.conf called
"hiddenmenu".  The way that works, when the GRUB screen comes up, it
says something about booting kernel-<some_version> in N seconds.  The
timeout is five seconds.  If you hit any key during that countdown,
you will get the normal GRUB menu with the choice of however many
kernels you have.

To go back to the usual GRUB menu, change this in
/boot/grub/grub.conf:

  timeout=5
  splashimage=(hd0,0)/grub/splash.xpm.gz
  hiddenmenu

to

  timeout=10
  splashimage=(hd0,0)/grub/splash.xpm.gz
  # hiddenmenu

If you want the older kernel by default, change the "default"
argument.  The kernel stanzas in grub.conf are numbered from 0, so you
probably want to change

  default=0

to

  default=1
