No, FFB isn't working. In Dirt2, the wheel seems to handle like it is a game pad (rigid turns) and none of the tweaks to change the strengths in the game appear to be working either. It appears as if the driver is designed for the xbox360 Gamepad which
just happens to work with the Wheel Controller too. I shopped around for other $100 $150 wheels but none have native (out of the box) support for Windows 7 64bit. I will just wait it out for the next generation of wheels which support Windows 7 natively.
Luckily for me, Dirt2 is the only game I've bought for the PC to test out 2D Surround with 3 monitors I've recently aquired. All my other racing games are on Xbox 360 for the big screen TV setup. I have a very excellent original Logitech Formula Force Wheel
that doesn't work with Windows 7 64bit so unless I dual boot with WinXP, that is a dinosaur play toy as well.
