/*	PROCEDURE TO REPORT NEW PCI DEVICES
 * We are trying to collect information on new PCI devices, using
 * the standard PCI identification procedure. If some warning is
 * displayed at boot time, please report 
 *	- /proc/pci
 *	- your exact hardware description. Try to find out
 *	  which device is unknown. It may be you mainboard chipset.
 *	  PCI-CPU bridge or PCI-ISA bridge.
 *	- If you can't find the actual information in your hardware
 *	  booklet, try to read the references of the chip on the board.
 *	- Send all that to [e-mail]
 *	  and I'll add your device to the list as soon as possible
 *
 * BEFORE you send a mail, please check the latest linux releases
 * to be sure it has not been recently added.
 *
 *        Thanks
