irda & ir-tools as debian packages can be found at :

ftp://ftp.debian.org/debian/dists/potato/main/binary-arm/misc

or one of it's mirrors

BTW I've got IR-comm to work with my 7110 :>
here's how :
- install irda & ir-tools packages.
- edit /etc/irda/drivers :
- set serial device to /dev/ttyS2
- set type to infrared
- start irmanager : irmanager -d 1
- install minicom ( or another terminal emulator )
- set minicom to /dev/ircomm0 19200 8 n 1
- and off you go...

AT-command summary can be found on forum.nokia.com

Good luck...
