 That's right. Actually there's no any differences - between "free" sectors
 to "empty entries". In most cases 128 entries will be sufficient I said
 before. And I know that's not preferred way to align partitions. But, GRUB2
 works even that cases. Of course that isn't GNU extension. Because of
 there's no any differences except total entry count, I think it should be
 work.
 
 I think there's some problem loading freebsd-boot partition. When I
 selected USB stick at boot menu, I can't see anything except black screen
 and it reboots immediately. If it boots correctly, it should display
 loading screen - rotating animation - and (if freebsd-ufs partition exists
 and /boot populated) Greeting message such as "BTX Loader 1.00 BTX Version
 is 1.02", then "Welcome to FreeBSD". I checked that behavior with work
 cases(128 entries, different boot partition's start location), and I found
 that it should display "rotating animation" even there's not exist
 later-step bootloader files in /boot; In that case, it automatically
 reboots after shows that animation because there's no freebsd-ufs partition.
 
 
 
 * I'm first use of FreeBSD's bug reporting system and it causes some
 confusion to me. I replied same mail to John, but not bug-followup system
 and I guess it is what my reply doesn't seen on bug tracking system. I hope
 that send reply mail to this address is right...
