You can boot with your md device with the following kernel command

md=<md device no.>,<raid level>,<chunk size factor>,<fault
yes and best is you compile raid in, so that boot can be also raided
Best for what ?
Who still uses RAID arrays without persistent superblocks ?
Who still uses RAID assembly by the kernel instead of mdadm ?
All this has beed obsoleted by the superblock format 1.x and the use of
an initrd or initramfs.
By the way, if you compile md in the kernel, you should also compile all
necessary host controller and disk drivers in. And expect failure with
current drivers which do not guarantee that a given disk gets the same
device name at each boot.
