Vista - Howto install unsigned driver on Vista x64 RC2?

How can I convince Vista x64 RC2 to install unsigned drivers?

"Bcdedit.exe /set nointegritychecks ON" seems to have no effect.

The driver for my Chipdrive smartcard reader is the most important one I
cannot install.
The following drivers for my Intel D975XBX mainboard do not install:
- Sigmatel Audio
- Desktop Utilities
- Destop Control Center
- Matrix Raid Manager

When your system starts to boot Hit F8 immediately. At the bottom of the
list is a disable signature option. Some report that you need to use this
for every boot thereafter to have the unsigned drivers load but I haven't
run into that situation for one of my hardware pieces.
