> Thanks for the backtrace, this seems to indicate that the fault is

> pScrn = xf86Screens[scrnIndex]; // does bad data get in here?
> pVidMode = VMPTR(pScrn->pScreen);
> pVidMode->First = pScrn->modes; // First set to Invalid pointer?
> pVidMode->Next = pVidMode->First->next; // Crash

> My guess is that adding a check for pVidMode->First would eliminate the
