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
