Indeed you have diffs at restore time.

Your restored fdisk gives:
Disk /dev/sda: 26.8 GB, 26843545600 bytes
255 heads, 63 sectors/track, 3263 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xde0eac79

mondorestore doesn't use the same number for end and start compared to your original fdisk. Which explains the "gaps" mentioned.
and that may also come from roundings due to the dfference of size.

You can always boot with nopart and do the partioning yourself.
