Intel Sandybridge and UMA: use mmio_resource()
With SandyBridge northbridge code, uma_memory_size was reset to zero before variable MTRRs were set. This means MTRR setup routine did not previously create a un-cacheable hole for uma. Keep the behaviour that way, mmio_resource() has a prerequisuite that the new region does not overlap with any cacheable ram_resource(). The result is not optimal setup in the number of used MTRRs, but continue with this approach until MTRR algorithm is improved.
