Ups. I did that with my user-account. Now with root:
lspci -v -s 5:0
05:00.0 PCI bridge: Integrated Technology Express, Inc. Device 8892 (rev 10) (prog-if 00 [Normal decode])
        Flags: bus master, fast devsel, latency 0
        Bus: primary=05, secondary=06, subordinate=06, sec-latency=32
        I/O behind bridge: 0000c000-0000cfff
        Memory behind bridge: fbe00000-fbefffff
        Capabilities: [70] Express PCI/PCI-X Bridge, MSI 00
        Capabilities: [90] Power Management version 2
        Capabilities: [a0] Subsystem: Gammagraphx, Inc. (or missing ID) Device 0000
