And it indeed fixes the parted_devices output (thanks for compiling
it!), but unfortunately not the partman dialog.  Because that gets the
info straight from parted_server in partman-md/init.d/md-devices:

        open_dialog PARTITIONS
        free_space=''
        while { read_line num id size type fs path name; [ "$id" ]; }; do
                if [ "$fs" = free ]; then
                        free_space=$id
                        free_size=$size
                fi
        done
        close_dialog

In the present case parted_server returns:
num=(-1) id=(0-4161535) size=(4161536) type=(primary) fs=(free) path=(/dev/md0) name=()
that is, it erroneously reports half the real size.

I could go on to replace PED_SECTOR_SIZE_DEFAULT with dev->sector_size
throughout partman-base/parted_server.c, but I'm getting suspicious.
Isn't there a good reason for this state of affairs?

Of course you guessed right.  Non-i386 people probably never forget
specifying their architecture...
