VirtualBox second screen problem

[dacrow]

hey people!

i'm ruuning mac os x in virtualbox and i got a problem. first my setup:

 

HOST:

win7 x64 with virtualbox 3.2.12

phenom x6 1055t

4GB ram (2GB for guest)

96MB graphics RAM for guest

 

GUEST:

mac os x 10.6.6 with 10.6.6 Legacy Kernel by nawcom

 

everything is running fine, i use the system to develop iphone apps with the ios sdk from apple.

 

it would be really helpful to get my second screen working under max os. i use the second screnn already under the host as "extended desktop". when i activate the second screen in the virtualbox properties of my virtual machine and i start the machine, a second window pops up. while in the first window my mac os is booting up, the second window remains black.

 

if i open the system properties in mac os (after mac os finished booting) and go to "monitors" there is no second monitor.

 

i search the forum and google, but i didn't find any help on this topic..

 

is there a way to activate the second screen in mac os? is a kext file needed for my kernel to let mac os know, there is a second screen (window)?

 

thanks for any help
