the detected geometry was not big enough to hold the imagefile. I guess I'll have to have a chat with the guy who made the imagefile to see if the image could be shrinked.
Thanks for the advice.

Btw, what limitations are there on the block size, and what drawbacks should I expect with a too large block size?

check disklabel to make sure the detected geometry is big enough to
hold the imagefile.  also, using rsd1 is the better device, and you
should specify a block size bigger than the default 512 to make it
faster.
