Exactly the same problem here (5.3-BETA6).
However, I managed to make the system bootable again by booting with
the fixit floppy and issuing "disklabel -B ad0s1".
Apparently the bde swap partition overwrote the bootstrap code of the
slice. This problem is severe, /etc/rc.d/gbde_swap should *REFUSE* to
enable a bde swap until it is fixed.

parameters extracted from in-core disklabel are:

Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:

Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
