strange gdm-binary

[red_alert]

hey guys

is it normal, that gdm-binary uses >50% (mostly about 60%) of my cpu? :-/

i'm running fedora core 2 test 2 (development - upgraded from fc1 via 
apt-get) on a dell inspiron 500m notebook with an 1400mhz intel centrino 
cpu.
i'm having this problem since fc1 (eventually after upgrading some 
packages from development, can't say if the problem existed at the 
beginning).

do you need any other relevant informations? (sorry, i don't know *what* 
  is relevant in this case...)

thx, regards
