I've had this when cables get kinked or mistreated in any way then crosstalk becomes an issue. Cat 6 is far more forgiving and should be used even for patch cables to guarantee the integrity of gigE.
Chris are they hand made cables or purchased ones of at least CAT5e spec
The other thing I have had is problems with cheap consumer Gig-E switches where they can just be a bit funny about exactly what NIC's will reliably link at 1000Base-T
I had a netgear switch for a while that would randomly decide that a couple of my machines only deserved 100Base-T. Power cycling the switch or changing ports would often cure it for a bit but the real cure was to replace it.
