I had a Boot Camp partition under Tiger, which I used with Parallels 5160 without any problems. Before I installed Leopard, I upgraded to a new harddrive, and copied an image of my old Boot Camp partition over to it. This partition works perfectly when I reboot into it, but Parallels, while recognizing that I have a Boot Camp partition, always gets an error when attempting to start it. I have tried bot 5160 and 5540 without any success...
