What I mean is that 8086 is all that is left, no device ID is patched in at all.
8086 is actually the Vendor (Intel) so it should stay as this.
I'm using iAtkos 10.5.7, I have replaced all the GMA* kext's with ones from the 10.5.7 combo update.
Another thing I have noted is that with stock kext's I am stuck with 1024x768 but the X3100 kext get's loaded.
The no cursor issue may be related to the white lines problem.
Could it be that the kexts are setting the external display as primary and the internal as a mirror display?
Is their a way of turning off the external display, I don't have the option in BIOS, mine is setup as a dual display in bios.
If I use the display switch button on the laptop the internal display switches off, and just wont cycle back to it, I don't have a external monitor to test.
