(Get the code!)
I have only booted off the 12.10 32bit iso so far and have not installed, but the black display problem with the emachines e527 with the 12.04.1 iso does appear to be resolved "out of the box" with the 12.10 iso, using no additional kernel parameters or other modifications. However, while pressing the FN+arrow left/right keys displays the brightness slider on the screen and the slider responds to key presses, no corresponding change in actual screen brightness occurs. Adding (as I'm doing in 10.04) acpi_osi=Linux to the kernel command line when booting Linux makes the brightness adjustable, but disables the gui brightness slider display entirely. On 10.04, with that kernel option my arrow keys are properly assigned for adjusting the brightness, while on 12.10 they're backward.
