I should have been more careful in my descriptions of the problem.

XFree86 4.2 ha an older version of the Render extension, (that does
not support the CompositeTrapezoids request). That's what's causing
the problem here.

I'll be fixing Cairo to support older X servers after I get back from
vacation next week.
