It turns out that FC5 and FC6 must have a gorked up S3 Savage4 video 
driver.  In the debugging output, I noticed the savage4_smbus was shown 
just prior to the crash on boot.  I renamed the driver (i2c-savage4.ko) 
to i2c-savage4.ko.orig and the machine booted just fine.  The Xinerama 
feature with multiple screens seems to work just fine without the driver 
so I don't know what the driver actually did for me.
