Yes it is possible with the new savedefault/fallback features. You need
the last version from CVS to do that. I tested this feature
successfully.

You need to read the documentation in the cvs version, in docs/grub.info
or docs/grub.texi, and search for the options "savedefault" and
"fallback", and "grub-set-default".

The fallback setting is usefull when grub fails to load a kernel.
The savedefault is usefull when a kernel panic. You may use the kernel
command line option "panic=10", if you use Linux, if you want Linux to
automatically reboot after 10 secondes of kernel panic.

Here is my menu.lst (for example).

default saved
fallback 0
hiddenmenu
timeout 10
foreground = 000000
background = c0c0c0
splashimage (hd0,0)/grub/splash.xpm.gz

title Terminal
kernel (hd0,0)/boot/default/vmlinuz root=/dev/ram0 init=/linuxrc rw vga=788
initrd (hd0,0)/boot/default/initrd
savedefault

title Test mode
kernel (hd0,0)/boot/test/vmlinuz root=/dev/ram0 init=/linuxrc rw
initrd (hd0,0)/boot/test/initrd
savedefault 0

title Administration
kernel (hd0,0)/boot/default/vmlinuz root=/dev/ram0 init=/linuxrc rw
initrd (hd0,0)/boot/default/initrd
savedefault 0
