Well, the cache key is the hostname/sysname as known by NAV, which ultimately comes from the PTR record for the device's IP address. If you change the casing of the PTR record in DNS, you also effectively invalidate the ipdevinfo DNS cache for that host.
I suspect that there is som kind of case sensitive comparison somewhere besides the cache.
All the troublesome devices I have found have a sysname like "roomb1000.domain" while the DNS RRs are "roomB1000.domain", both A and PTR.
