Subject: 2.6.20.git regression: 'PCI: add the sysfs driver name to all
	modules' causes hard hang on boot

Greetings,

Per $subject, git.yesterday hangs hard on boot here. A git bisect
fingered the commit below, which I verified via git bisect reset; git
revert -n 725522b5453dd680412f2b6463a988e4fd148757, after which box
boots fine.  (well, I hope I verified... i'm git-ignorant)

commit 725522b5453dd680412f2b6463a988e4fd148757

    PCI: add the sysfs driver name to all modules

    This adds the module name to all PCI drivers, if they are built into the
    kernel or not.  It will show up in /sys/modules/MODULE_NAME/drivers/

    It also fixes up the IDE core, which was calling __pci_register_driver()
    directly.
