Most recent kernel where this bug did not occur: 2.4.*

Distribution: All distro's using 2.6 kernel

Hardware Environment: 
Intel P4 3.0 ghz 800 Mhz FSB (1mb l2 cache)
Asrock intel 865 chipset P4i65 Motherboard with AGI 8x technology, 1GB Ram 
Leadtek Nvidia Geforce 6800 GT (256Mb).  
Suspected due to Patented Asrock AGI 8x technology

Software Environment: 
Install Time. Unable to go past the installer. Either i get the following kernel
traceback error (please see below) or in some distro's such as ubuntu and SuSe
when finished and booting into the system hangs at 
starting hotplug subsystem..
In SuSe I used NOHOTPLUG=1 as kernel parameter and booted in. In ubuntu I booted
in using my onboard gfx card and removed the hotplug.sh file in /etc/init.d/
directory, then booted normally with my gfx card.

Problem Description: 
When i try to install any GNU\linux distro when using an AGP graphics card using
a 2.6 kernel i get the following kernel crash and kernel freezes to go past to
the installer. 
The following is a traceback from Fedora Core 4 installer.
After,
starting /sbin/loader
