You can use md device for /boot, and LVM for the rest.

Vladimir I like the idea of mirroring the /boot device witd md as it's the only partition i don't have under lvm control, and the rest just mirror with lvm.

is this the way you are doint it ?

Yes, that is the way I am doing it.
I did it in some RedHat installations.
And it works OK.
