My worry is that this delays the setup of the IRQ and DMA to very late in the process, possibly after the quirks have been run, which can be problematic. We have platform hooks that might try to "fixup" specific IRQ issues on some platforms (especially macs) which I worry might fail if delayed that way (I may be wrong, I don't have a specific case in mind, but I would feel better if we kept setting up these things earlier).
