Have you set the partition types to 0xfd ? Are you using a dos partition
table ?
I guess you are using an sgi disklabel - and the sgi code misses the
call into the raid layer in case there is a raid partition.
You might want to try this patch against current 2.4 cvs

Its completely untested (compile wise and i did not run it)
Tell me if it helps.
