LZO as hidden option has no practical sense. Although LZO should be
auto-selected when some dependent project is selected (e.g. reieser4)
- there should be separate patch for this. Mixing such changes with
'core' LZO patch will just add side noise.

Ok, I will do this.    I wonder if some difference in opinion in such
things can actually cause 10+ extra RFCs?
