Thanks for the recommendation on ENV{REMOVE_CMD}.  With some minor
modifications to my old patch, I've got it working using ENV{REMOVE_CMD}
now reliably post suspend.

Although rewalking the child devices to find the right one to prod might
seem tedious, it should be more future-proof in case later hardware ends
up changing.

Would you mind reviewing the attached patch for submission to udev then?
