[Grml] Normal user not permitted for pci scan

[T]

Hi, 

when I tried to use the xvidix driver for mplayer, I get
"Error occurred during pci scan: Operation not permitted" error for 
normal user, but root is ok. 

How can I fix it? 

PS. my groups:

groups=4(adm),5(tty),6(disk),8(mail),9(news),10(uucp),20(dialout),21(fax),22(voice),24(cdrom),25(floppy),26(tape),27(sudo),29(audio),30(dip),33(www-data),60(games),100(users),110(scanner),118(plugdev),120(camera),135(fuse),143(nvram),65534(nogroup)

PPS. Working log:

Adding the -v option didn't get me much details:

Here is the result when the above command is ran with root:
