I then installed CentOS 6, and, since to my understanding thunderbolt support is only in more recent kernels, I went ahead and upgraded the kernel to version 3.18.4 from ElRepo. However, I have not seen any indication yet that Thunderbolt is working - although I may just not be looking in the right place. Over on Google+ Greg Kroah-Hartman indicated that I need the PCI hot plug controller driver enabled, and Matthew Garrett indicated that I specifically need the ACPI PCI hotplug driver rather than the native PCIe hotplug driver. To check, I ran the following command:

Yep, if you need the ACPI PCI hotplug driver, CONFIG_HOTPLUG_PCI_ACPI
should be enabled. I think you should be able to use "make
menuconfig" to enable it at:
Bus options
Support for PCI Hotplug
ACPI PCI Hotplug driver
I'm not RedHat/CentOS person, so I don't know the distro details, but
I would try "make install" as a starting point.
