For future's sake, if anyone else experiences the same, only replace the pins that are broken.. No point in unsoldering and resoldering the ones that are still good.
A friend of mine snapped two edgemost IDE pins off his A1200 mobo, so I just removed the stubs, used a desoldering pump + braid to clean out the holes and then stuck in and soldered two pins I took off a suitably sized pin strip.
