raid and lvm are different storries, although lvm can do striping.
I think reiser only had problems with raid5.

A lot of places to change for the current dbootstrap. Trust me I
hunted them all down to get devfs working.

Anyone who wants raid/lvm/other fancy stuff on his root partition
should have a bit more ram than lowmem users. Also note that lvm on 7
is not possible without initrd tricks (which is rather stupid of lvm).

If all else fails, take some out of swap.
Is ramfs swapable? If so, just use that.
