I have the same specs in my hp and you have a US model. I havent been able to install the appleworm disc, all i get after the loading is a black screen, seems like it goes into the installer but it is unable to display. I used the flags that you posted and its still the same result. I have the 6770m, bios: InsydeH2O Ver. 03.60.48F.1A
I installed from a flash drive after restoring from a DVD. I believe the only kernel flags I used were cpus=1 and GraphicsEnabler=no. Try these in various combinations and see if they help: busratio=12 -v -f PCIRootUID=1 arch=x86_64. If arch=x86_64 doesn't work, try arch=i386. The flash drive boots up the installer every time for me, it was more difficult to get it to boot after the install. Good luck.
