You're right that at the moment that suspend code is broken for NOMMU.
However, Will Deacon has a patch to fix it in his nommu branch on
kernel.org:
https://git.kernel.org/cgit/linux/kernel/git/will/linux.git/commit/?h=nommu
I'll let Will comment on how/when he might look at proposing that code
to be merged.
