That's unusual behaviour.  Normally U-Boot is prone to going to poweroff
then for some reason, but not hang.  And as you say -->

| Does any of this provide any clues on what might be happening on my GTA02?

It ties into my current misery with Glamo very well.  I can make a guess
about what is happening, somehow the framebuffer region has become
deadly to touch and it jams down nWAIT permanently when you do so.
Currently I routinely see this on resume on 2.6.26 which has a large
patchset on top to solve the device tree issues we always had, when I
force my way in to see what it is doing, it is locked up in the
framebuffer cursor code making the cursor flash.  But I never saw it
with our canned U-Boot or Kernel driver init for Glamo.

It's another straw in the wind, thanks for the report (although I dunno
what it means yet).

What is on the LCM at that time, is it all white by any chance?
