I've installed iAtkos L2 on this computer, I've seen others reporting their success stories on this computer with lion, and considering the hardware it should work out of the box, but they never seem to have encountered this issue.

Take a look at the screenshot.

Any idea what's wrong here? I can't find any ElliottForceLegacyRTC.kext on the computer, in /S/L/E or /Extra, just to begin with.
