Lenovo ThinkPad X60: Native VGA init: Disable i915 interrupts.
Without that fix the i915 linux kernel driver prints(but still works):
i915: render error detected, EIR: 0x00000010
i915: page table error
i915: PGTBL_ER: 0x00000013
[drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking
i915: render error detected, EIR: 0x00000010
i915: page table error
i915: PGTBL_ER: 0x00000013
