Getting rid of SYSFS xserver-xorg-input-wacom error log during Debian Squeeze boot up

I have a system upgraded from Lenny to Squeeze and every time, during boot up sequence, I am seeing the log below:

SYSFS{}= will be removed in a future udev version, please use ATTR{}= to match the event device, or ATTRS{}= to match a parent device, in /etc/udev/rules.d/z60_xserver-xorg-input-wacom.rules:11

I don't have a wacom device really, so I just decided to get rid of this error message. To do so, do:

#: aptitude remove xserver-xorg-input-wacom

Then, delete file z60_xserver-xorg-input-wacom.rules from /etc/udev/rules.d

Is this the right way to do it? I don't know :)
