How can you enable it? It's not obvious from the compilation instructions.

Compile SBCL with the command ./make.sh --with-mark-region-gc and the resulting build will use the mark-region GC. (Picking the GC at start-time instead of build-time would be very nice, but technically hard to pull off unfortunately.)
Also don't forget to clear your FASLs since they're not compatible. e.g. remove ~/.cache/common-lisp/sbcl-2.4.4-linux-x64/ and ~/.slime/fasl/
