here's my experience of using the 64bit drivers on an imac-24 purchased December 2007 with bluetooth k/b and mouse.
Ran bootcamp assistant and created partitions and started installtion of Vista Ultimate 64-bit edition.
When it came to selecting regional settings and timezones etc..the apple bluetooth k/b and mouse would not function (obviously).
Plugged in Dell USB keyboard and MS intellimouse from PC and the worked almost instantaneously, so proceeded with install at this point.
Vista installed without issue.
first time entering vista i wanted to run bootcamp and get the drivers so had to download a sub-set of the vista 64bit drivers from a torrent, this activated bluetooth k/b and mouse so off with the USB k/b mouse.
Could not get vista to recognise my ATI RADEON HD 2600 PRO card even with native drivers from ATI, so proceeded to torrent the bootcamp64 executable and ALL the drivers this time.
Turned off UAC in Vista and ran bootcamp64 with installed bootcamp on Vista and all the relevant drivers..presto, everything works now like a charm...no need to use and mobile modders or stuff like that.
scores on the doors after install were:
Processor 5.3
RAM 4.8
Graphics (AERO) 5.9
Graphics (GAMING) 5.3
H.Disk 5.5
Spec is imac-24" alu 2.4Gig, 320GB HD and 2GB RAM
Hope this might help somebody out who wants to do similar, only one issue I'm aware of and that is when you hold the option key on reboot to select the O/S to boot to the bluetooth mouse does not seem to work, so I use the bluetooth k/b arrow keys and return to select the O/S.
(my reason for doing this was the p!ss poor performance of Vista Ultimate 64-bit under VMWARE fusion 1.1)
