Aha I have not really used ArrayFlatten, but that makes the problem relatively trivial to do then. Just Flatten/ArrayFlatten everything, use LinearSolve, then Partition. Okay that's not too bad, especially since the matrix doesn't need to be partitioned again. I wonder if such a problem has a name, I can't imagine this is uncommon.

More general block matrices can be converted to a a single large matrix with ArrayFlatten. In the end, such a task has to be done since LinearSolve uses external libraries which expect a matrix as input.
