Latest version is 1.1, not 1.0

I have a macbook 4,1 model. (intel c2d 2.4, intel gma x3100).

It has 64 bit processor and 64 bit EFI. It's capable but graphic drivers (for the GMA X3100) are NOT 64bit. I tried to enable 64bit with no success. Boot load time increased from 40 seconds to 1:30min. After selecting back 32bit the boot went to normal.

I think 10.6.2 MIGHT have new 64 bit (graphic) drivers, so 64 bit kernel could be enabled.
