searching "grub-reboot" for gentoo

[c0balt]

Hi,
I often need to do something while rebooting my pc (like getting a cup of coffee^^), thats fine if Im rebooting gentoo (which Im not doing often because its stable^^). Problem is if I want to reboot to WindowsXP I have to stay and wait for the grub screen. Other Distros have implemented features so that one can choose which partition should be rebooted (afair the script is called "grub-reboot" on debian, mandrake does it through KDM afair), is there a similar feature for gentoo?
(I searched the forums a little and had a look at the handbook, didnt find anything)

thx in advance
