Will not work on my system, but I haven't spent a lot of time on it yet.

Works. I changed the default in the code to 1 to enable it all the time
(it can still be set to 0 [disabled] by setting it with insmod).

I looked and saw nothing else that might help me out. I did quickly scan
the rest of the code and added the AMD-762 ID and description (BTW,
anyone know what the REAL name of the MP chips are? I used Irongate MP),
and changed the description for the GeForce ID to something more
meaningful, to produce the following:

[root@keroon /root]# cat /proc/nv/card0 
----- Driver Info ----- 
NVRM Version: 1.0-1251
------ Card Info ------
Model:        GeForce3 DDR
IRQ:          17
------ AGP Info -------
AGP status:   Enabled
AGP Driver:   AGPGART
Bridge:       AMD Irongate MP
SBA:          Supported [enabled]
FW:           Supported [disabled]
Rates:        4x 2x 1x  [4x]
Registers:    0x0f000217:0x00000304
[root@keroon /root]# 

I also managed to get it to work with the NVidia AGP driver (as opposed
to agpgart), but still without FW. I swear FW works on my A7V133 with
this same video card.



Alan,

   I created a new file - amd7411.c - based upon the previous file for
the AMD7409. I added IDs to pci_ids.h, pci.h, etc. in an effort to
support the different AMD devices. My kernel loads the AMD7411 driver
now, but does not enable DMA, etc., although using hdparm to enable
everything seems more reliable now.

Below is the output from lspci -vvv and lspci -x for my system as it
sits now. (Hmmm, looking at it I think I mis-named a couple of the
devices. Oh well - too much work, too little sleep [thank you SirCam,
Code Red, et. al] :)
