There may be more than one underlying reason for these various
problems we are seeing.  This one might be cured by

  xsrc/external/mit/xorg-server/dist/Xext/sync.c

revision 1.1.1.1.2.1 aka. 1.2, which entered netbsd-5 on March
18.  The commit message points to

  https://bugzilla.redhat.com/show_bug.cgi?id=474586

which mentions the gnome screen saver triggering this problem.


However, even though I used code from after this date from the
netbsd-5 branch, I was still seeing consistently higher than
expected CPU load in my Xorg process.  I may have found a
workaround for my problem, though -- in my case it helped to
force the radeonhd driver to use the older XAA accelleration
method, and not the newer EXA method, by doing:

Section "Device"
  Driver "radeonhd"
  Option "AccelMethod" "XAA"
EndSection

I must admit that I do not have any idea about what the deeper
reason was for the observed behaviour prior to applying this
config change.
