You need to be able to act with the raid in the same way the bios does or you can't boot. I don't think geom would easlily do that but I could be wrong. Certainly if you treat teh ata raid as just a bunch of striped disks, then the bios will not be able to boot off it. of course don't take my word too seriosly asn I'm not running an ata raid system at the moment.
