With Lion and Mountain Lion, you can start the BootCamp installation application and you are presented with the choice to only download the latest Apple hardware drivers and install them on a disk or flash drive. You can exit after you have done that.
Once your standard Windows install is finished, then you can run the hardware driver disk to finish the Windows installation just like with any other motherboard.
I think there was a warning in the BootCamp Windows installation instructions about having too many partitions for the Windows installer which would necessitate temporarily removing some drives during the installation which could be replaced once your Windows installation is up and running. This applies to a conventional Windows install as well (plus it prevents you from accidentally formatting and installing to the wrong partition or drive.)
