hum... It maybe best(In the other side, fixed size block io unit is
easy to handle in some situation). If core team don't mind file system 
modification, I will try(not so difficult, just merge two method)
though it will require modification for DEV_BSIZE dependent part.

BTW, i have modified sys/dev/vnd.c and vnconfig.c to support disklabel
feature. I will send-pr if this problem settled.

Also, sbin/disklabel.c needs modification to support non-512
bytes/sector media too.
