pci-e, does my laptop have it?
 
I'm slimming down my kernel and I'm wondering if I can pull pci-e support out of my configuration.
does anything other than video cards use that bus?

PCI-e is PCI Express. That's the only type of PCI expansion bus I see in your lspci output.

Try this for more detail. It'll also show you if you have any PCI-e slots in use.

Code:
dmidecode -t 9 | grep -E "DMI type"\|Usage\|Type

PCIe can also be used by network, sound, RAID cards and other stuff as well.
