This is off the cuff, but try this from the grub command line:

root (hd0,2)
image (hd0,2)/initrd.img
boot

HOWEVER, because you have a seperate boot partition, root may need to be 
set to (hd0,1), and the image may need to be set to whatever the image 
name is in your /boot partition (initrd.img-2.6.8-1-686, for example).  
Autocompletion should work from grub, after you set root to (hd0,2) - 
try typing image (hd0,2)/ and then pushing tab.
