Anyone, would you try to make GEOM_DDF1(4)?

Hi GEOM Developers.
I'm using HP Proliant DL140G3 with Adaptec HostRAID (SATA).
But I couldn't make FreeBSD 6.2-R install CD probe RAID1, so
I researched DL140G3's RAID system(Software RAID). As the
result, I understood that Adaptec HostRAID supports DDF
format[*1].

I was trying to make geom_ddf1(4), but I couldn't make it,
it's too hard for me:-(. So, anyone, would you try to
make geom_ddf1(4)? Of course, RAID1 support only OK! :D
I have two real DDF1 data from configurated SATAs(/dev/ad4
and /dev/ad6 are RAID1 mirrored) like following way[*2][*3].
And I confirmed no configured SATAs filled all NUL(0x00) on
DDF1 Anchor.

http://people.freebsd.org/~nork/DDF1/ad6-last6k.img
*NOTE* Please restructure ad?.img from ad?-last6k.img
I made a test program[*4]. I got a result of /dev/ad4.
Please see also following[*5].
