Description of problem:
Benjamin Herrenschmidt has brought sleeping back to Apple's current
line of PowerBooks and iBooks. In anticipation of this getting into
the mainstream kernel, it would be nice if the Fedora Project provided
a pmud package. Pmud, a daemon that performs power-related functions
on Apple computers, is provided as an RPM package by Yellow Dog Linux 4.0.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Notice that closing the lid on a G4 iBook does not put the computer to
new package request -- reassigning to distribution.
For the record, Ben's kernel patch is available at
patch adds support to the kernel for the power management unit in G4
There is a newer patch vs. 2.6.9 available at
http://gate.crashing.org/~benh/albook-ibookg4-sleep-7.diff. When he
released this patch, Ben said:
> So here's the new patch, it replaces the previous one for Aluminium
> PowerBooks, and is still against 2.6.9. I'll do something against
> 2.6.10 when that one is out (it's a bit late to get that merged with
> Linus, 2.6.10 is in freeze mode now) and I hope to get all of that

So perhaps we will see this stuff in the Fedora kernel once 2.6.11 is
It looks like Ben's patch is in 2.6.11-rc3. The ChangeLog says:
> [PATCH] ppc32: pmac sleep support update
> This patch updates the PowerMac sleep support. [...]
I'm not averse to pmud if we're shipping PPC for FC4.
Apmud is now in Fedora Extras and the Fedora kernel supports power managment on
new Apple computers.
