Never heard of it before - if its useful to support it, then do send
patches...
$ time lzop <ramsave >ramsave.lzo
real 0m13.515s
user 0m7.500s
sys 0m1.340s
$ time gzip -c <ramsave >ramsave.gz
real 0m46.327s
user 0m37.690s
sys 0m1.360s
$ ls -lh ramsave ramsave.lzo ramsave.gz
-rw-rw---- 1 fvte fvte 707M Aug 26 22:26 ramsave
-rw-r--r-- 1 root fvte 282M Aug 27 17:48 ramsave.gz
-rw-rw---- 1 fvte fvte 330M Aug 27 17:47 ramsave.lzo
