Can you or Felix try again with cvs?  Unfortunately I don't have an
integrated savage to test on and savage4s don't seem to have the
problem.

Xv should work now on savages with the "old" streams engine.  the
problem was the FIFO was being setup wrong for vertical interpolation.
 Vertical interpolation is also very bandwidth intensive and one of my
savages4s isn't up to it, so I've disabled it by default for all "old"
chips.  It's now available as an XV attribute
(XV_VERTICAL_INTERPOLATION) you can turn it off and on on the fly. 
After some testing I may enable it by default on some chipsets.

Thanks,
