[ale] md w/raid 0 before LVM?

[ale at advancedopen.com (Brian W. Neu)]

to store snapshot data, I put a physical volume on top of a raid 0 and 
extended the volume group onto it.

the problem is that as far as boot sequences go, it looks like only raid 
1 mirrors are started before lvm -- and since a physical volume is 
missing (since the raid0 hasn't been initialized), the volume group 
doesn't start -- hence the machine doesn't boot.

Does anyone know a way to get the kernel to somehow do this, or is it 
truly impossible?
