Sure, good idea. I've been running with this reverted recently.

That shouldn't be necessary if you can suspend-resume with
7503bfbae89eba07b46441a5d1594647f6b8ab7d reverted and the USB controller
modules unloaded.
Instead, with 7503bfbae89eba07b46441a5d1594647f6b8ab7d reverted, please write
'disabled' to the /sys/devices/.../power/wakeup files of all USB controllers
and see if suspend-resume works in this configuration.
Thanks,
Rafael
