lspci -v shows this:

02:05.0 PCI Hot-plug controller: Compaq Computer Corporation PCI Hotplug
Controller (rev 12)
        Subsystem: Compaq Computer Corporation: Unknown device a2f8
        Flags: 66Mhz, medium devsel, IRQ 66
        Memory at f7bf0000 (32-bit, non-prefetchable)
        Capabilities: [58] Message Signalled Interrupts: 64bit+
Queue=0/0 Enable-


I can see that it is 66MHz but I'm not sure about the 32 (or 64) bit
part.  I guess that gigabit will be an improvement here.
