For getting the crash dump out of the swap partition
and into /var/crash ( replacing the: ???? ) with
its analysis:

# savecore /var/crash /dev/????
# crashinfo -b=20

(I think that last will automatically pick up the latest
saved core. Otherwise add the path to the dump file after
the -b argument.)

See:

man 8 savecore
man 8 crashinfo

Note that /var/crash/ would need to be writable. For
single user mode, you first need to deal with making
it writable as I remember. This gets into your
partitioning and mount point usage and ZFS vs. UFS.
If everything is in one UFS partition, then:

# mount -w /

should be sufficient, as an example.
