Only 1920x1440 resolution in Windows 7 with iMac 27" 2010

Question

Only 1920x1440 resolution in Windows 7 with iMac 27" 2010

Hello guys!
I have this annoying problem when running Windows 7 via Bootcamp. I can't set my resolution to 2560x1440 which is the native resolution. I have installed the Bootcamp drivers from the Mac OS X Snow Leopard DVD, but no matter what I do, it's impossible.
If you have a solution, or just a good suggestion, please reply.

Anders

I forgot to mention it's the 32-bit version of Windows 7

The iMac I am pretty sure needs the ATI Catalyst driver, and you really want to get rid of Apple driver.

Such a basic and simple question deserves a tech note under Apple's Boot Camp Support, don't you think?

+My iMac (27-inch, Late 2009) displays a black screen during installation of Microsoft Windows 7 using the Boot Camp Assistant. How do I fix it?+

The Windows 7 installer does not include required graphics or Bluetooth drivers for this computer. To obtain the necessary drivers and resolve the issue, see this article (creating the SD card and drivers for the "black screen" issue).

Guys, sure no one have any ideas about this?
I really need the native resolution.
Thanks!

Guys, as far as I can see, Apple have only made boot camp drivers for iMac 11,1.
And now since I have an iMac 11,3 I'll have to wait for the next update.

New Macs have more current Boot Camp 3.x drivers.

And none of them are perfect.

Also, BC 3.0 came out before Windows 7 was done, BC 3.0 is now old, and it isn't possible to just get the latest 3.x and install it, only installs over the older versions. Why? to insure Snow Leopard license (preventing getting the latest and direct install).
