Turns out using nvalias instead of devalias makes it permanent.

So I now boot to grub directly with an nvalias hd /pci.... set and
boot-device set to hd (which means boot the PReP boot partition).

I now have to set root manually to (md0) and then load /boot/grub/grub.cfg
as a configfile.  Then I can boot.  The fat partition is now needed
at all.  The grub image has mdraid, raid and ext modules included in it
and then dd'd to the PReP partition.

So how do I convince grub where to look for the config, or should I
create a small config file that sets the root and loads a config file
and embed that in the image perhaps?
