I'm trying to install the Mountain Lion on my notebook Acer Aspire 5750 / 5750G. The installer just boots when the kexts AppleIntelHD* and AppleIntelSNB* (or something) are deleted from S/L/E, and boot to installer with -x -v PciRoot=1 GraphicsEnabler=No

After install boots only with PciRoot=1.

Feedback after install:

Sound: No
Video: Only 1024x768, recognized only 64MB, slow speed.
Webcam: Yes
Microphone: No
Battery: No

One more thing:

I updated the BIOS to version 1.20. I don't know if this will help.
