udevadm monitor and atapi dvdrw

[Franco Martelli <martellif67@gmail.com>]

Hi everybody,

I'm using Debian Sqeeze 6.0, kernel 2.6.32, udev version 164.
With kernel provided from debian my dvdrw is under scsi subsystem and 
udevadm monitor recognize optical disk change with a lot of info output 
suitable to write rules.
I've recompilated the kernel and things has changed, now my dvdrw is 
under ide/atapi subsystem and the device name is hdc now.
I'd like to write a rule that remove udf and crc_itu_t modules as soon 
as optical disk is left off from dvdrw drive. Example:

SUBSYSTEM="block", KERNEL="hdc", ACTION="change", RUN+="/sbin/rmmod 
udf crc_itu_t"

I look at http://reactivated.net/writing_udev_rules.html but doesn't 
help for ide devices ACTION="change".
Could anybody help me to write such a rule?

bye,
