Hello again,

i seem to have found the solution to my problem, and i am now seeing this in 
the syslog (which is correct):

"[geobackend] Parsing IP map zonefile
May 20 11:39:17 ns1 pdns[2487]: [geobackend] Finished parsing IP map zonefile: 
added 93357 prefixes, storedin 231491 nodes using 2777892 bytes of memory
May 20 11:39:17 ns1 pdns[2487]: [geobackend] Parsing director map /etc/geo-
May 20 11:39:17 ns1 pdns[2487]: [geobackend] Finished parsing 1 director map 
files, 0 failures"

what i did was remove the zone and geo-map files from the pdns.d dir, and place 
them recursively in the /etc dir instead. now everything seems to be fine.

next step is to configure the zone RR's. :)
