Yes, that seems to work as well. Although there are two minor things I
- First, intel_generic_setup sets num_aperture_sizes to 7, while the i830
has only 4 valid values (32 to 256 MB).
- Second, when intel_generic_configure clears the error status register, it
resets bits 8, 9 and 10. With an i830 it should clear bits 2, 3 and 4.

So I'm not sure if this works in general, or could it cause errors on other
