I can confirm that this new code runs at the same speed
as the current lzo code in the Linux kernel on
my ARM926EJ-S based platform.  I only tested decompression,
using the attached hacky userspace code.

   # time ./lzo-bench/old/unlzop <lzoimage >/dev/null
   real    0m 0.29s
   # time ./lzo-bench/new/unlzop <lzoimage >/dev/null
   real    0m 0.29s

   (where lzoimage is a Linux Image compressed with lzop)

So, from my side there are no more objections.
Thanks for doing this work, Markus.
