Quoting Bojan Smojver <bojan(a)rexursive.com>:
Just a quick note that this one (from testing) appears to be much
better
than 1447 in terms of ACPI on my notebook (HP ZE4201). Battery reporting
appears to work properly, even after suspend-resume cycles and there are
no more strange clock issues.
Huh, I may have spoken too soon here. Better, but not perfect. There are
still problems, but I'm not sure what they depend on. Sometimes ACPI
stuff comes back OK after the resume, sometimes it doesn't. Removing
ACPI related modules and restarting acpid doesn't always help when the
weirdness happens either. Who knows, maybe 2.6.13 will be better...
