Coprocessor and SM bus controller drivers

My system:
As Rock K10N78M AM2+ Mobo
AMD Athlon 64 X2 Cpu
Nvidia GeForce 9500 GT video card
Windows XP Pro 32bit

I just reinstalled Windows XP on my system due to slowness issues I was having. After re-loading and installing all drivers including Nvidia driver I stilll have two devices that do not have drivers and show as not functioning in device manager.

1. Coprocessor
2. SM Bus Controller

How/Where can I get drivers for these devices?

More specifics on the devices:

Coprocessor PCI\VEN_10DE&DEV_0753&SUBSYS_07531849&REV_A2\3&267A616A&0&0B
SM Bus Controller PCI\VEN_10DE&DEV_0752&SUBSYS_07521849&REV_A1\3&267A616A&0&09

I went to Nvidia's website and used the auto driver detection tool which suggested I download the Nvidia storage drivers. This worked wonderfully and after loading the device manager problems went away.
