In the past, under Fedora (8) distributions, I have recovered from
improper video driver configurations (for instance, installing an
improper proprietary video driver and relevant modules for Compiz or
Beryl special effects) by renaming the /etc/X11/xorg.conf file to
something else.  Upon rebooting Fedora, the operating system would
"automagically" (or semi-automagically --for some user input may be
required ) go through the X configuration procedure and recreate
another /etc/X11/xorg.conf file --reverting to default Fedora open
source video drivers and relevant support, evidently.

However, the fact that avahi and/or hal fail to start probably
represent only symptoms of another(s) more serious issue(s) and quite
possibly the procedure I described above may only serve as
"interesting" insight.  However, if the procedure works, please make
sure to back up your /etc/X11/xorg.conf file, as Mark suggested.

Wish you good luck, Ms Doll.
