From 54c990775f78113a708f24e15877f6b7bd9a1277 Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Mon, 2 Jul 2018 04:21:19 -0400 Subject: macintosh/via-pmu68k: Don't load driver on unsupported hardware Don't load the via-pmu68k driver on early PowerBooks. The M50753 PMU device found in those models was never supported by this driver. Attempting to load the driver usually causes a boot hang.
