Excellent, that fixes my problem :) I can now boot of a gmirror
device, hurrah :)

I still have applied the root_mount delay patch. From what I can make
out this is only necessary if I need to boot off a degraded mirror, so
I should be able to remove that.

I'm not really sure if this really has much bearing on anything, but
my devices at the moment appear to be da1a, da1c, etc, when I'm
configuring up the mirror. If nothing else, it appears that gstat
doesn't recognise those so monitoring their activity is difficult.
Would it be better to configure the mirror in a slice, so using
something like "gmirror label -hv gm da1s1", or does it really make no
odds at all?
