If the "configure_cisco7970.pl" wasn't call, you wouldn't see asking for "English_United_States/7980-kate.xml", do it WAS called.
It's the one which created a SEP<MAC> file in /tftpboot and correct entries in /etc/asterisk/sccp.conf.
Please check is asterisk is running
ps auxww | grep asterisk
then run as root
asterisk -rx 'sccp show devices'
As far as I know those files (lack of them) should not cause any problem, but the fact that it keeps asking for them says that you probably have a outdated firmware of the phone.
We are using chan_scpp in asterisk, and the author of it ALWAYS asks if you are running latest firmware from Cisco because looks like the first versions of firmware for 7970 are pretty buggy.
We can not distribute the firmware that is known to work, so you should get it from Cisco (another posibility is to connect to a call manager which has latest firmware). This operation should be done once, and after that the phone will continue to run latest firmware.
