Suspend/Resume on Thinkpad x40

[Joe Snikeris]

Hi all,

First off, I apologize if this is not the right forum for this
question.  I was torn between posting this in mobile, ACPI, X11 and
here.  If I might get a better response in one of those forums, please
let me know and I'll post there instead.

I'm having some trouble getting the kinks worked out of the
suspend/resume functionality on my laptop, an IBM Thinkpad X40.  It is
mostly working now, but I am still experiencing some strange behavior.
 I can suspend and resume from a console just fine (except for the
fact that the console comes up blank and only displays new
characters); however, suspending and resuming in X is problematic.

The first suspend and resume in X works perfectly, but the next time I
hit suspend, the machine locks up while still displaying whatever I
was doing in X.  Note that if I switch to a virtual terminal before
hitting suspend, this problem does not occur.  Does anyone have any
suggestions on what I might do to get this resolved?  The details of
my machine follows; please let me know if any additional information
would be helpful.
