I do not enve know how to make "dangerously dedicated" disk, and the 8.0 may do this sliently.

ad0 had three DOS partitions (slices),
S1 for DOS
S2 for FreeBSD 7.2
S3 for another FreeBSD

When boot to 8.0-Beta{3, 4}, 8.0 sees not partition, which means 8.0 looked at a wrong location for partition table.
After did partition (slices S1 for FreebSD and S2 for nothing) and 
Label (Unix partitions, failed to find device node /dev/ad0s1b in /dev),
content of 7.2 is gone.

But, the original partitions are still in the MBR (S1 for DOS, and S2 and S3 for FreeBSD).
