	0+1 is cool if you do a mix of hardware and software. It's
a good compromised between the supposed "security" of hw raid, and
the performance of software raid.

	0+1 all software is workable too, just dont try it on
a 2.2 kernel (on 2.2, you can set it up and run it, but if you lose
anything, it's not reentrant and everythin dies. ooops). It reportedly
works well on 2.4 (havent tried this myself, we tend to stick to
1 or 5, and the occasionaly 0)
