Fedora 18: Lock up on boot of kernel 3.7.2-201 on Dell Optiplex 755 -- KMS

[Robert Knight]

After installation of F18 from DVD and an update, several Dell Optiplex 
755's failed on reboot with a garbled display and frozen system.  These 
all have the "Intel Corporation 82Q35 Express Integrated Graphics 
Controller (rev 02)" display controllers.

Booting with "nomodeset" parameter prevents this.

I don't see anything in Bugzilla, but I'm finding it hard to believe I'm 
the only one with the problem.
