Unfortunately, I'm not at all familiar w/ the process. I'm going to pick at it a few more days, but will probably end up having to punt and dumpsys onto a 512n or AF-512e device. But, since you are refactoring all this code in -CURRENT anyway, I think it would be awesome if you could look to the future and make it work w/o assuming that dump device block size is DEV_BSIZE; it would be better to use the sector size, as returned (for example) by ioctl(DIOCGSECTORSIZE).
