[Hampshire] current kernel on Sarge

Can anyone tell me what kernel Sarge, last updated about 3 days ago, would be
running?

I have foolishly mucked up a new installation on hdb in my husband's box - and
messed up Grub, so that I can't access the perfectly good sarge installation
on hda as a protem solution to his box being usable. And because I can't
access it, I can't just run uname -a. :-(

TIA
