A319 Captain experiences an FMGC2 failure enroute that is unrecoverable. Safe landing ensues at destination with the First Officer's ILS manually tuned.

Narrative

At FL330; First Officer lost FMGC2. FAA Inspector in jumpseat watched as we navigated through the systems to determine landing capability at destination. Weather was low overcast at 600 FT 2 miles visibility. We called Dispatch and Maintenance to help with FMGC problem and answer from Maintenance was not acceptable to FAA Inspector about limitations of the aircraft. We determined with the FMGC failure; no First Officer ND map; no #2 VOR; no #2 ILS; that we could fly a Cat I ILS. No status message was displayed until we started the final approach segment even though I activated and confirmed the approach to force FMGC into Approach Mode. I had to manually tune the ILS. On approach; First Officer's airspeed momentarily jumped to 260 KIAS then indicated approximately 15 KTS below Captain's; Captain's standby airspeed read correctly throughout approach and landing. During landing rollout V1 inoperative message displayed on First Officer's PFD. Normal landing. Aircraft write up was completed and report sent at request of FAA.
