Sorry I missed this before.  That sounds like an excellent idea for a
kernel patch.  A kind user on the linux-arm-kernel@ list[1] recently
mentioned he'd be willing to test patches, if you need a guinea pig,
and I assume once a patch is written and tested it should be possible
to get useful feedback from the list.

Thanks,
Jonathan
