That's referring to booting a kernel *directly* from a RAID 1 (mirror) set.
Alpha, pmax and vax (hmm.. should update that man-page, I guess :) )
boot blocks know how to grab a kernel directly from a RAID 1 set.
I believe i386 boot blocks are somewhat aware of this as well.
On other architectures, you (currently) need some other way to load a
kernel... but after that, the root filesystem can be on a RAID device.
(Note that none of the architectures are able to boot a kernel
residing on a RAID 0 or RAID 5 set..)
