Wohoooo...

ray@ is the man!!!

He has some hacked up version of lzma at  http://zrouter.org/hg/zrouter/

and using that lzma for compression, I finally was able to boot:

Mounting from ufs:/dev/map/rootfs.uncompress failed with error 19.

Loader variables:

Manual root filesystem specification:
  <fstype>:<device> [options]
      Mount <device> using filesystem <fstype>
      and with the specified (optional) option list.

    eg. ufs:/dev/da0s1a
        zfs:tank
        cd9660:/dev/acd0 ro
          (which is equivalent to: mount -t cd9660 -o ro /dev/acd0 /)

Now,  will look into why "Mounting from ufs:/dev/map/rootfs.uncompress
failed with error 19."
