Dear ovi1,
I used the boot pack from the supported model page in the wiki... Yes... I had issues with wifi when I tried to run the installer usb (instead of turning off the wifi I actually move the IO80221Family.kext which is the same i think). But then, when lion finished install, the IO80221Family.kext did not caused any kernel panic even when my intel wifi is on.
By the way, did you rebuilt your extension.mkext after booting into os x lion for the first time and installing edp 2.2? For the first boot I used -x -f but after rebuilding my mkext I just booted normally?
Some kext don't load up even if we use -x -f and only load up after we rebuild it and boot normally like speedstep and volume!
Cheers!
