Yeah you have to edit the disktab file to specify the block size to vnd.
I believe this is enough:
4k:\
:se#4096:
vnconfig -t 4k vnd0 /xyz/blah
Then the "on-disk" label can take over to describe your partitions and the
disk size. vnconfig won't load the partition offset/sizes anyways, you would
have to use disklabel -w or disklabel -R to write the partition info to the
"disk".
