Why not fix the reporting problem by patching the bug submission tool
to check for duplicates? It would be a useful feature more generally
in other cases too surely?

I have a patch for this, adding support for more recent kernels in
testing/development with the upstream authors at the moment, but there
are a number of non-trivial changes in code that may have usage cases
I'm not aware of or subtle bugs in corner cases so I'm awaiting an ACK
from them to proceed.
