Yes, but the problem is that /proc/pci exists even if
CONFIG_PCI_OLD_PROC is not set:
[root@manjak /root]# ls -l /proc/pc*
-r--r--r-- 1 root root 0 Jan 27 21:11 /proc/pci

But you can't access the file:

[root@manjak /root]# cat /proc/pci
cat: /proc/pci: Bad file descriptor

[root@manjak linux]# grep PCI .config
CONFIG_PCI=y
CONFIG_PCI_BIOS=y
CONFIG_PCI_DIRECT=y
CONFIG_PCI_OPTIMIZE=y
# CONFIG_PCI_OLD_PROC is not set
CONFIG_BLK_DEV_IDEPCI=y

IMHO /proc/pci should have been removed if CONFIG_PCI_OLD_PROC is
disabled. I don't know if it is a bug or feature ?!

Ok, I haven't been reading linux-kernel for 36 hours. It's a loong
time in kernel development, isn't it ? ;-)
