2.4.25 kernel: suspend causes freeze on iBook2

Hi all,

I am running sid and just installed Sven's 2.4.25 kernel (package 
kernel-image-2.4.25-powerpc-pmac) on my iBook2.  It works perfectly 
with one unfortunate exception: the laptop does not wake up from suspend 
mode when I re-open the lid.  The monitor displays only a pattern of 
vertical colored bars, and it does not respond to any keystrokes (aside 
from the Apple reboot sequence), nor can it be pinged.  This is completely 
repeatable, and it happens whether or not I am running X.

I never had this problem before (upgraded from self-compiled
2.4.20-ben10).  I should note that my previous kernel used devfs but the
kernel of Sven doesn't appear to.

Any ideas?  My video hardware (according to /proc/pci) is a Radeon
Mobility M6 LY, and I load the following modules via /etc/modules at boot:
udf, evdev, dmasound_pmac, agpgart, radeon, tun, mol.
In /etc/yaboot.conf I have (snipped):


I get a message at boot that the agpgart module does not exist, but I
don't know if this also occurred with my previous kernel (having already
deleted it).

I have installed Michael Daenzer's drm-trunk-module-src package, version 
2004.02.28-2, compiled and installed the drm-trunk-module-2.4.25-powerpc 
package.  I also have pmud version 0.10-6 installed and running.  
/dev/pmu has permissions of 600, owned by root.root.  pmud config files 
are unmodified, except for /etc/power/levels, which reads:


Thanks in advance for any help,
