Boot from MD RAID possible?

Linux doesn't usually support the format used by the Windows driver, but you can run the normal linux software MD RAID which works just fine. The few real SATA RAID controllers like 3ware are supported. If one uses MD RAID, would one be able to mirror the boot partition? Is it possible to create multiple MD RAIDs on 1 pair of disks such as separate RAID1s for /boot, / and an LVM vg and a RAID0 /space filesystem?
