This problem existed before my patch, I just moved the line to another file.
To fix it, one needs to test on real hardware and figure out what is supposed
to go in there.

The bug was apparently introduced in linux-2.5.70 in this commit:

commit 2b1a7e97c8c2d6330a432cbcaf83a0ef5fab848e

    [PATCH] fix m68knommu DragonEngine2 target setup code

    Numerous fixes for the m68knommu DragonEngine2 setup code.

    It was out of date relative to more recent kernels.  Original patches
    from Georges Menie.
