The computer with the Intel 815 worked with the PCI coding problem. The 
security update and the fix for the Intel driver was successful with the 
Intel 865G. Thanks for the quick resolution to the problem.

With the security update out of the way and the pci code cleaned up a 
bit. It still makes sense to split up the driver into 815, 830 and 915 
to allow code to be taylored for each card that has different 
capabilities. It also makes sense since older generations of Intel video 
cards won't burden the advancement of next generation cards by needing 
code carried on to maintain workability for the older chipsets.

When the code was broken for the 810/815 portion of the driver, my 865G 
video card started working and the random lockups ceased for the 865G. 
Fortunately, when the code for the 810/815 was fixed, the 865G still 
remained lockup free.

With the latest breakage for I830 and above video cards while the Intel 
815 worked in my tests, the thought of splitting off the driver for low, 
medium and higher capability seperate drivers came to mind again.

Also, when the i810 driver was broken for the Intel 815, I chanced 
across a website that provided seperate drivers for the i810/815 and 
another for the 830. I believe there was a seperate driver for the Intel 
915 on the snapshotted drivers page.

The driver on that site worked to bypass the problem. I can't remember 
if it was the refresh or the total breakage of the driver. I believe a 
change was made in the driver code for dual head with the 830 card at 
the time the driver broke for the Intel 815 video my computer has as 
builtin video.

Just a though since I feel the scheme would be better.
