Snow Leopard with dual GPU + Win7x64 dualboot

[KHIT]

Hey

 

I have recently bought a HP dv6-3160 laptop, with Intel Core i5 460M 2.53GHz. I have succesfully installed snow leopard on it, and got 10.6.5 working with iUpgrade 10.6.5 legacy kernel.

 

On my HDD i have two partitions made by Windows:

 

SYSTEM(System, Active, Primary) Windows has placed my bootmbr on this partition

 

OS (Boot, pagefile, Crashdump, Primary)

 

Then I've got 1 Mac OS Extended (Journaled) partition, named Macintosh HD.

 

My computer has switchable graphics, so that I cam switch between my Intel HD(64MB) and my ATi 5650(1GB). In windows this works fine, but in SL, I can only use the Intel HD Graphics. I know that the new MacBook Pro also has switchable graphics, so this function should be accesable in 10.6.5, but it isn't. My system is installed by using iATKOS S3v2, and [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] to boot the installation disk and first boot of the OS. Then I installed Chameleon by using the [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] app, to make sure that it didn't overwrite/change my Windows bootmbr, because I want to make the dualboot through the Windows 7 boot manager, but now I have to press enter on the first screen with he HP logo, or else the machine will freeze and I need to press ctrl+alt+delete and restart, to enter my system, also after I've deleted OSX and the Macintosh HD partition.

 

Any suggestions to solve my problem?
