'k, I've tried to search google (even with site:http://www.nvnews.net to narrow 
it down), and I'm drawing a blank, so I'm asking here ...

I picked up a nice new system the other day, 64bit, Dual Core and running 
6-STABLE on it ... 7900GS Dual DVI video card ... now, I've read/know about the 
64bit issues with the driver, but from what I've been able to tell, I should be 
able to do this with just the nv driver that comes with X.Org 7.x ...

Now, I've included my current XF86Config file ... it starts up X, but on the 
second monitor, it looks like I'm getting a mirror of the first monitor, but 
all 'low res', for a lack of better way to describe it, and 'flashing' ... for 
instance, if I move the browser window right-left on the 'good screen', the 
'bad screen' shifts right-left also, to match ... so I'm obviously missing 
*something* important here

The only way I could get the current configuration to even start, without 
getting:

Fatal server error:
Requested Entity already in use!

was by changing the BusID to PCI:1:0:1 (or anything) even though nothing seems 
to turn up in pciconf other then pci:1:0:0 ...

none1@pci1:0:0: class=0x030000 card=0x221f19f1 chip=0x029210de rev=0xa1 hdr=0x00
vendor = 'NVIDIA Corporation'
class = display
subclass = VGA

So, the question is ... what am I missing, or is the nvidia kernel driver a 
requirement to getting dual-head working after all?
