The version now in Debian unstable is 7.5 and it still depends on HAL.

The libudev patches were still being revised as of a few weeks ago: the
latest stable X server does indeed still depend on HAL. But you can
configure it out (and given how crashy HAL is I do so as a matter of
course: say what you like about libudev it's never caused programs to
coredump on me).

You would be amused to see what havoc udevd and xorg are causing for people with Fedora 12 on some Intel integrated graphics chipsets.

Somehow X, udevd, and apcupsd of all things are going crazy on my media-center PC after every reboot. I have to kill off the udevd processes and sometimes apcupsd in order to get X to stop re-detecting its outputs in a flood.

It's not an xorg or a udev issue - a bug in the kernel is causing the hotplug interrupt to fire
continuously, which results in the kernel delivering millions of messages to userspace. These are
processed by udev, which understandably consumes CPU in the process.

The dependency on hal is gone since xserver-xorg 1:7.5~2.
