Nothing wrong with adding the drivers post W7 install, however it's impossible to speculate whether updates or any other aspects of functionality would be as per normal if you installed using the method on the link within this thread.
Hitting F6 early on in setup, whilst it harks back to the earliest days of SATA, does allow you to load the drivers before the OS itself - and arguably there can be no cleaner environment.
What narks me is that Microsoft couldn't be bothered to include the drivers on their DVD disks for W7, and engineer setup to optimise AHCI when suitable SATA controllers are detected as being present.
