Please send me the dmidecode and acpidump information for your X40, I want
to have a look on what the video module could be doing that messes with the
firmware switching...

That's quite a typical problem on firmware switching, yes.  The ATI X300
version of the T43 can do it, depending on the resolution in use, but that
means little for older versions of the firmware, OR for thinkpads with
different GPUs.

Very well.  For now, I will just make video optional and I will put its
conversion to sysfs in the backburner TODO list, and get to it eventually.
I won't remove it.
