Haven't been fully following this thread, but I'll note I experienced
some APM/X related freezing with early versions of X 4.  I disabled 
power management in X and the problem went away:

In /etc/X11/XF86Config:

...
Section "ServerFlags"
        Option "BlankTime"       "10"
        Option "StandbyTime"     "20"
        Option "SuspendTime"     "25"
        OPtion "OffTime"         "30"
        Option "NoPM"            "true"
EndSection
...

I've since commented out the 'Option "NoPM"  "true"' line, and the
problem hasn't occurred again.  Also, seems there may be some issue
between the X server and the xscreensaver in this regard.  Currently
have the X 4.0.3-4 (sid/unstable version) installed.  The "disagreement"
seemed to be more kernel/X than BIOS...

Maybe try disabling the Power Management in X?
