The current emulated HW runs at around 200mhz or something horribly slow.

OpenSUSE don't do native compiles with OBS. They use distcc or
something like that to cross compile some of their architectures. It
was developed as part of the Intel/Nokia MeeGo use of OBS. Fedora has
a requirement of native builds. Stage1/2 of a Fedora platform bring up
can be cross compiled but we're now into stage 3 which is native
builds. Fedora also has over double the amount of source packages to
OpenSUSE and we're working with upstream to get fixes upstream (both
Fedora mainline upstream and projects upstream) as we go rather than
forking and fixing later all of which ends up being more time
consuming in the short term but less overall.
