Normally, checkpoint_segments can help absorb some of that, but my experience is that if I crank the number up, it simply delays the impact, and when it occurs, it takes a VERY long time (minutes) to clear.
There comes a point where your only recourse is to throw hardware at the problem. I would suspect that getting faster disks and splitting the checkpoint log to its own RAID partition would help you here. Adding more RAM while you're at it always does wonders for me :-)
