Anyone successful with Acer Aspire 7740G?

[Desttro]

Hi,
I have Acer Aspire 7740G, this spec:

CPU: i5 -430M, 2533 Mhz
Graphics: ATI Mobility Radeon HD 5650
Monitor: Samsung 173KT01-A01 (17,3 inches)
Audio: Realtek ALC670
WLAN: Atheros AR5B93

I used to install OS X 10.8.4 via USB with "uni.be. ast" - success, but when I'm going to use "mul. ti beas.t", install Chimera, or with Chameleon Wizzard chameleon, laptop will not boot up.
Resolution not working to native 1600x1200 and sound.

Is there someone, who can post DSDT, his bootloader, kexts, etc.?

Thank you very much!
