Can I install an older version of grub using a newer one?

Hi listers.

I have a back-up that contains stage* files from grub 0.92. I do a bare 
metal restore using the latest Knoppix CD which has grub 0.93. Last 
thing before reboot, still in the Knoppix CD, I do grub, root() and 
setup() and there are no errors reported. Yet upon next reboot there is 
no grub prompt just the cursor in the upper left corner of the screen 
and ONLY a reset can make it tick again! So my question is, should this 
kind of setup (install an older version of grub using a newer one) work 
or not? I mean, does it lock after reboot because there is a bug in grub 
0.93 or because a 0.93 can not corectly install a 0.92?
