You're talking about upgrading the kernel and leaving it to do its first boot 
unattended?   Well, sure, if the symlink's been amended, it should do that.

But then, if you don't have a symlink, surely you'd just need to amend the 
kernel name in  menu.lst   instead, and leave it to boot just the same?

(Though personally, if I'd made a significant change like that, I'd want to 
watch it boot).
