Ok, I found that the problem is caused by pktsetup which I compiled from 
the cvs sources.
Perheaps the cvs sources are not so up to date with the new pktcdvd 
kernel module, so I downloaded and installed udftools-1.0.0b3-9
i386 deb package and everything turned bright.

Being a Fedora user and not wanting to mess with the debian scripts 
included in the package I added these lines to my /etc/modprobe.conf:

# PACKET WRITING:
alias /dev/pktcdvd/0 pktcdvd
alias block-major-252 pktcdvd
install udf     /sbin/modprobe --ignore-install udf; \
                /usr/local/bin/pktsetup 0 /dev/dvd

In this way everytime /dev/pktcdvd/0 is mounted I get my dvd device 
correctly mapped to pktcdvd. It could sound as a sort of kludge but it 
works.
Thanks to everyone who put me to the right direction to solve the problem!
