OK, I have examined the board and I most definitely have the Intel 
82801BA I/O Controller (ICH2).  When I do an lspci,I get:
[root at houlnx hotplug]# /sbin/lspci
00:00.0 Host bridge: Intel Corporation 82815 815 Chipset Host Bridge 
and Memory Controller Hub (rev 04)
00:02.0 VGA compatible controller: Intel Corporation 82815 CGC [Chipset 
Graphics Controller]  (rev 04)
00:1e.0 PCI bridge: Intel Corporation 82801BAM PCI (rev 05)
00:1f.0 ISA bridge: Intel Corporation 82801BA ISA Bridge (ICH2) (rev 05)
00:1f.1 IDE interface: Intel Corporation 82801BA IDE U100 (rev 05)
00:1f.2 USB Controller: Intel Corporation 82801BA(M) USB (Hub A) (rev 
05)
00:1f.3 SMBus: Intel Corporation 82801BA(M) SMBus (rev 05)
00:1f.4 USB Controller: Intel Corporation 82801BA(M) USB (Hub B) (rev 
05)
01:05.0 Ethernet controller: Intel Corporation 82557 [Ethernet Pro 100] 
(rev 08)
01:08.0 Ethernet controller: Intel Corporation 82801BA(M) Ethernet (rev 
03)

 From i2c-801 in doc/busses:
"If you do NOT see the 24x3 device at function 3, and you can't
figure out any way in the BIOS to enable it,
(and especially if you have an Asus P4B board),
see prog/hotplug/README.p4b."

So I went and read README.p4b and followed the instructions there.   
Here is a cut and paste of the setpci:
[root at houlnx hotplug]# /sbin/setpci -d 8086:2440 f2.w
0060
Problem is 0x60 already has bits 3 and 8 cleared.  What do I do now?

Thanks
