PCI device order problem

["H. J. Lu" <hjl@lucon.org>]

In arch/i386/kernel/pci-pc.c, there are

/*
 * Sort the device list according to PCI BIOS. Nasty hack, but since some
 * fool forgot to define the `correct' device order in the PCI BIOS specs
 * and we want to be (possibly bug-to-bug ;-]) compatible with older kernels 
 * which used BIOS ordering, we are bound to do this... 
 */

static void __devinit pcibios_sort(void)

The problem is on my MB:

Eth1 becomes:

and eth0 becomes:
03:07.1 Ethernet controller: Intel Corp. 82546EB Gigabit Ethernet Controller (rev 01)

Is that a good idea to have an option to sort the PCI device by PCI bus and
slot numbers?
