Tyan Titan Pro (?) natoma chipset P6 motherboard

>Description:

It seems that one of the chip ID's has been lost somewhere, so that a
device has a description in -stable but not -current.

>From a 2.1.5-RELEASE boot message on the machine:

Aug 20 22:00:24 news /kernel: Probing for devices on PCI bus 0:
Aug 20 22:00:25 news /kernel: chip0 <generic PCI bridge (vendor=8086 device=1237 subclass=0)> rev 2 on pci0:0
Aug 20 22:00:25 news /kernel: chip1 <Intel 82371 PCI-ISA bridge> rev 1 on pci0:7:0
Aug 20 22:00:25 news /kernel: chip2 <Intel 82371 Bus-Master IDE controller> rev 0 on pci0:7:1

Now running a -current from a week or so ago:

Aug 24 16:31:42 news2 /kernel: Probing for devices on PCI bus 0:
Aug 24 16:31:42 news2 /kernel: chip0 <generic PCI bridge (vendor=8086 device=1237 subclass=0)> rev 2 on pci0:0
Aug 24 16:31:42 news2 /kernel: chip1 <generic PCI bridge (vendor=8086 device=7000 subclass=1)> rev 1 on pci0:7:0
Aug 24 16:31:42 news2 /kernel: pci0:7:1: Intel Corporation, device=0x7010, class=storage (ide) [no driver assigned]

Notice that chip1 (on the motherboard) is not being identified as a
PCI-ISA bridge anymore. Either 2.1.5 is ID'ing it wrong, or -current doesn't
have the chip id code for some reason.

>How-To-Repeat:

Play with a natoma based motherboard under both 2.1.5 and -current

>Fix:

Add the chip id to the table in -current, or fix the id code in -stable
