As I saw there :
http://lists.freedesktop.org/archives/hal/2006-August/005777.html
The event chain goes like this :
  kernel -> udev -> hal -> dbus -> g-v-m -> dbus -> hal -> kernel
Since we are only changing udev, I thought the problem should be in
udev->hal communication, and that hal needs to be updated somehow.
But I have not found how to debug hal, to be sure hal is indeed the
problem and that it does not see the udev event.

I also checked if there were any hal git commits related to udev, and
found a recent one :
http://gitweb.freedesktop.org/?p=hal.git;a=commit;h=f6af40c1e7ea54e69eb2d259d91dd212065d5f6e
But I re-introduced the udevinfo symlink (ln -s /sbin/udevadm
/usr/bin/udevinfo) and it did not help.

I can reproduce this with the 126 version made by Aaron, the 127
version made by Tobias, and my own nearly vanilla 127 version
(on this note, I don't know why Arch has to change so many things from vanilla).
