hald hitting ACPI files in fc4t1

[Pete Zaitcev <zaitcev redhat com>]

Hello:

I installed fc4t1 and noticed that totem's video stutters quite a bit.
Sometimes the keyboard input in gnome-terminal feels lagging, too.
It turned out that hald was causing it. Running strace on it showed
nothing more than periodic access of ACPI files in /proc. My hypothesis
is that these accesses cause AML interpreter to work.

I have two questions. Is this something new or interesting (e.g. do you want
a bug)? And, can something be done about it (can it be made to poll once a
minute or so)?

Greetings,
