Yes, on this hardware, the kernel is smashing the last few stolen
entries with a bad value, so running a new driver against an old kernel
will fail as well. There's not a lot we can do about this direction
though; until we have all of this hardware management in one place,
we're stuck trying to synchronize fixes across two code bases.

I haven't even received my x200s yet as they've just entered production.
The problem here was that the prototype hardware had a different
behavior than what is now shipping, so we didn't catch this mistake
until the first production machines were tested.

If you care to try the above fix against your current driver sources,
that would be helpful for us.
