    The bisection turned up commit ea1441bdf53692c3dc1fd2658addcf1205629661
    "x86: use bus conf in NB conf fun1 to get bus range on, on 64-bit" as the one
    causing problems.

    Unfortunately, I can't revert cleanly it, because there are two more commits
    depending on it in a highly nontrivial fashion, so I have reverted all three
    commits

    a365998cd2cecfb827469dbd57c29602c106cb83
    44f7f90fbe7a3a99aab082f765346514b7b5c705
    ea1441bdf53692c3dc1fd2658addcf1205629661

    and X starts again. Also, suspend to RAM works from under X.

    Thanks,
    Rafael
