Suspend to disk on Laptops?

[Tom Reinhart]

I have a Dell Inspiron 8000, with a suspend to disk feature.  When the 
suspend is activated, it writes the memory contents into a special 
partition, marks the partition as active, and shuts off the machine.  To 
resume, the machine boots from the s2d partition, and makes the OS partition 
active.

In order to be able to resume, I have the following commands in my grub.lst:

title=Linux
root (hd0,1)
kernel /boot/bzImage root=/dev/hda2
...
title=Resume from Disk
chainloader (hd0,0)+1

This works, but is awkward because I have to remember which option to 
choose.  Is there any to make this more automatic?  What I would like is to 
be able to conditionally modify the menu based on whether the active 
partition is hd0,0 or hd0,1, and only present the Resume from Disk option as 
the default when hd0,0 is active.  Are there any plans to support this kind 
of feature?  I think that conditional menu modification is a fairly generic 
feature that could find a lot of applications and expand the utility of 
Grub.
