Attached is what I consider only an RFC patch.

I've not really thought through (to my satisfaction) the re-purposing of
current->keep_capabilities in the non-filesystem-supporting-capability
configuration, but this is basically the code I'm thinking about. (I'm
typing this email from a system running this patch over 2.6.23-rc3-mm1
so its not 'obviously' broken.)
