Installing Debian Squeeze on new I7 Core Dell Latitude E65, was easy. Installation went through ok, but after installation has finished, the X would not work.
You can find details here:
Some details on fixing X was to login, and replace Xorg.conf.
After getting the X to work, this is a great machine, fast, and with best operating system there is no limit to what you can do.
Enjoy your Dell Latitude E6510 !!!. I am!
