[MinnowBoard] Max PXE Boot?

I managed to get the original MinnowBoards to netboot with version 1.00
firmware, but it did take a bit of legwork - I'm using a GRUB image, and
there's a race condition between GRUB using the EFI network stack and the
UEFI firmware responding to ARP requests that causes GRUB to hang. I got
around it by editing the GRUB source to detect that particular condition
and simply retry (a bit of a hack, but it works). Don't know if this is
what you were running into...
My problem is that I'm trying to upgrade to the Minnow Max, but am having
trouble even enabling netbooting to try it - I used the 'bcfg boot mv'
command at the UEFI Shell to change the boot order to netboot the original
MinnowBoard, but the bcfg command appears to be unsupported in the Minnow
Max firmware.
