No this has nothing to do with the PCI issue, since the iMac can't  
HAVE a PCI card in it.

Look in your system log to see if there are errors at about the  
shutdown time. You can trash the energy saver prefs file to reset  
everything to the defaults, and check that there isn't a firmware  
update for this machine, as many of those dealt with power management  
settings.
