Here are the dts files I've been using for the NOR (1001) and NAND
(1001N) models of dreamplug; they look a bit different than yours.
Also, I've got no patches in the mge driver these days, but I do live
with the fact that I have to have cables plugged into both ports or
there are annoyingly-long timeouts trying to DHCP at boot time.
In fact, the only patches I'm using for dreamplug are the attached dts,
and personal kernel config choices, plus the one I posted about a week
ago to leave the cache allocate-on-write feature set the way the
bootloader set it.
I'm currently running -current _at_r243920 on dreamplug.
