Udev rules broken

Hi !

A few days ago I did a pacman -ySu but I ran into some problems.
After updating xorg and catalyst graphic drivers my X was "broken" (xinerama/xrandr related issues). So before I did a 'pacman -ySu' I saved my local database with 'yaourt -B backup.tar.bz2', after trying to get X to work I decided to resotre the backup. To make it short, I think  I completly messed up pacman. So after that I redid a 'pacman -ySu', but it was annoying me with the 'file exist' thing, so I did 'pacman -ySuf' which overwrited existing files. And I ended up with some "hidden" issues, like the 'core/dbus' package being installed (according to pacman), but files like '/usr/lib/libdbus-1.so' where missing (I had that for few packages, but since it only appers when I'm actually using theses packages, there might be a lot more to come). Reinstalling thses packages solves this problem.

So that was the context, in the case my problem could be related to this.
The problem is, I'm using AutoFS and udev to auto-mount my usb keys and external hard drive.
Udev creates a special node in '/dev/' (e,g, for my usb key it creates '/dev/usbstick') and AutoFS then automatically mounts /dev/usbstick to /media/key.
It used to work perfectly but after that upgrade (I also installed hal and acpid in the meantime), it doesn't seem to work. The node '/dev/usbstick' doesn't get created.

Here is the rule I'm using to do so:
/etc/udev/rules.d/07-key.rules

$>cat /etc/udev/rules.d/07-key.rules                                                                                              
ATTRS{product}=="Flash Drive", KERNEL=="sd?[1-9]", NAME="%k", SYMLINK+="usbstick", GROUP="storage"
ATTRS{product}=="USB Flash Memory", KERNEL=="sd?[1-9]", NAME="%k", SYMLINK+="usbstick", GROUP="storage"

So with this only, udev is supposed to create a node in '/dev/usbstick' right ?
But 'ls /dev/ | grep usbstick' returns nothing.

Udev is running correctly:

$> ps aux | grep udevd                                                                                                         
root       818  0.0  0.0   1852   716 ?        S<s  16:26   0:00 /sbin/udevd --daemon

Here is dmesg's output:

$>dmesg

And udevadm info's output:

$>udevadm info -a -p `udevadm info -q path -n /dev/sdd` | grep ATTRS{product}                                                      
    ATTRS{product}=="USB Flash Memory"
    ATTRS{product}=="EHCI Host Controller"

Thanks!
