I'm sorry I wasn't clear enough in my previous post. 

I don't use lvm on /boot, because when I read the HOWTO neither grub nor lilo 
could manage that. Haven't checked if that's changed.

In this particular setup, the swap partition is also non-lvm, and these are 
the two only non-lwm devices in my HD.
