What you can do is backport the platform-support on top of rev initially
marked good (in a branch named say foo) and when asked for testing do:

	git merge --no-commit foo
	<test>
	git reset --hard
	git bisect {good|bad}

Assuming the platform-support got in in one go (and you shouldn't test
in the middle, which you can simply skip), the merge should always work
just fine.

Best regards
Uwe
