 									<ul>
 										<li>It's commit aaecdf61 (drm/i915: Stop gathering error states for CS error interrupts)
 										in linux that introduced the regression</li>
+										<li>
+											This patch linked on the bug report page above:
+											<a href="https://bugzilla.kernel.org/attachment.cgi?id=172941">https://bugzilla.kernel.org/attachment.cgi?id=172941</a>
+											- fixes the problem, and makes the i945 laptops boot up again.
+											<ul>
+												<li>
+													Parabola has temporarily merged it in a kernel update
+													- when it's merged upstream, let Emulatorman know (#parabola on IRC freenode)
+												</li>
+												<li>
+													So has Guix
+													- when it's merged upstream, let mark_weaver know (#guix on IRC freenode)
+												</li>
+												<li>
+													Still waiting for jxself to merge it in freesh
+													(as a temporary stop gap, until the patch lands in linux upstream/mainline)
+												</li>
+											</ul>
+										</li>
+										<li>
+											Since 3.19, there are still some warning messages now, after applying the patch.
+											See Mono's comments on the bug report page

+											TODO: this fix in linux is a workaround, the real bug is in coreboot. (without the patch,
+											3.19/higher doesn't boot on coreboot/libreboot i945 with native graphics, but does boot
+											on lenovobios with 3.19/higher - it probably also boots with coreboot+vgarom, since
+											the bug is in the video init code.
