Hmm, does this kernel work with "MBR partition"?

Give it a go :)

Have I to install both at once?
After I installed the kernel it says "reboot". After that Hackintosh doesn't boot ...

Install kernel > cancel reboot > install kext > reboot now.

You may need to boot with -f switch after this.

Okay, thanks! And 9.5 is the Voodoo kernel, right? :-/

Yes, it's Voodoo kernel.

Good luck.

Voodoo kernel doesn't work with MBR partition :-(

Is it possible to make dual boot with GUID partition? :-/

I had the same problem and found a solution.
 

I had the same issues with USB devices not being recognized unless they were plugged in at boot. As mentioned in the posts above, a mismatch in version numbers seems to be the most common cause. I found the below post over on InsanelyMac Forums extremely helpful with instructions on how to diagnose whether a mismatch in version numbers is the problem and also how to correct the problem with files provided.

This was posted in March and there may be a more up to date fix. Most of the people experiencing the problem had installed Kalyway's 10.5.2. AMD which by default installs 9.2.0 Sleep Kernel & 9.2.2 system.kext.

Good luck

Now I'm on Voodoo (GUID) and always the same problem :(

System.kext & Kernel are matching versions?
