I have also had similar problems, although not necessarily after suspending for
a long time. Using ps aux in another virtual terminal, I could see
xscreeensaver-command processes hung from before going to sleep. I suspect a
race condition due to the "&" at the first line of
/usr/share/acpi-support/screenblank .

Could you guys please check next time this happens, if there is
xscreensaver-command processes around ? And if so, try removing that "&" ?
