J's kernel works OK with the PMU chip in my PB 150 (see log below). I
also tried it on a Duo 280c, but it usually shuts the screen down when
the PMU driver loads but not always (see log below). That doesn't stop
ADB from working correctly however...
It turns out that a workaround for the Duo 280c is simply remove the call
to pmu_enable_backlight(1) from pmu_init().
J, can you please try this on your powerbook?
I'll try out a PMU version query, as Brad suggests, to see if there is a
permanent fix.
