The latest 2.2.18-lvm0.9 patch (in CVS) contains new code which will allow
LVM to stack on top of software raid.  This code has had very little
testing outside my own machine so use with caution, that said I think
it'll work fine.

You cannot stack software raid on LVM for the 2.2 kernels.

I believe LVM0.9 will happily stack on top of software raid for 2.4.

Can I re-iterate that 0.9 is beta software, if this is production
system use 0.8final.
