Ok, then "-x" booted up.
First, try to know which kernel are you using to boot:
1 . Boot "-x"
2. login an then open Terminal app
3. type "uname -a"
That the line with kernel name and others info.

Besides that, type at boot after "-x" debug=0x100, so when you the KP, shows up some info, about what cause the KP.

Have you already chck the forum for other users with running MacOSX with similar hardware???
They already know what to use to get that hardware working.
