Our boot-loader is looking for /boot/ directory on <disk>s<X>a, right?
If so, you have to teach geom_mbr, that it should create slices for
providers from you class. I've such a patch ready for GEOM_MIRROR:

--- geom_mbr.c  12 Feb 2004 22:42:11 -0000      1.56
+++ geom_mbr.c  25 Jul 2004 14:26:05 -0000

	gp->dumpconf = g_mbr_dumpconf;
	gp->ioctl = g_mbr_ioctl;
	do {
-		if (gp->rank != 2 && insist == 0)
+		if (gp->rank != 2 &&
+		    strcmp(pp->geom->class->name, "MIRROR") != 0) {
			break;
+		}
		error = g_getattr("GEOM::fwsectors", cp, &fwsectors);
		if (error)
			fwsectors = 17;

The only thing which is missing here is a big /* XXX */, but this way
was suggested by phk.
I need to add GEOM_LABEL here as well...
