Well, since we are *not*  that linked to Mandriva, we could avoid this
problem by producing a netbook edition if needed. Why restricting our work
to i586/x86-64?

For some programs, there is a significant boost in using sse/sse2 (for
instance the mlt library, povray rendering, etc).

I've enabled them explicitly in mandriva some time ago in the x86-64 build,
and it should be the default there. If some arch do not comply to the "sse2"
demand, then we can discuss this on a "specific basis, but not limit
everyone on this...
