IIRC git-bisect just does an outright linearization of the whole tree anyways, which makes git-bisect work everywhere, even in the presence of difficult cross-merges. On the other hand, if you are git- bisecting ACPI changes (perhaps due to some ACPI breakage), and ACPI has 10 pulls from mainline, you _also_ have to wade through the bisection of any other changes that occurred in mainline, even if they're totally irrelevant. This is why it's useful to only pull mainline into your tree (EX: ACPI) when you functionally depend on changes there (as Linus so eloquently expounded upon).

Cheers, Kyle Moffett
