Again tried installing over iAtkos Lion, but system is unable to get boot loader with black screen.

Tried fresh installation with the help of Unibeast + Multibeast and myHack 3.1 finally system stuck :

ACPI_SMC_PlatformPlugin::start - waitForService(resource Matching (AppleIntelCPU Power Management) time out

May be the my hardware setup not supporting Mountain Lion. If some body know some tips please share with me.
