NVIDIA Start Xorg Without Monitors

Question

I'm running Redhat 6.4

uname -ra
Linux host.domain 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux

The graphics card is an NVIDA Tesla C2075, Driver Version: 319.37

Here's the problem I'm trying to solve:

I'd like to be able to boot my server with no monitor attached. At a later time, if I plug monitors in I'd like to be able to see the graphical display.

Current Behaviour:

Xorg terminates because it doesn't detect any monitors. I am unable to get anything at all on the screen.

Xorg.0.log:

X.Org X Server 1.13.0
Release Date: 2012-09-05
[    31.569] X Protocol Version 11, Revision 0
...
[    34.279] (EE) Screen(s) found, but none have a usable configuration.
[    34.279]
Fatal server error:

Please consult the Red Hat, Inc. support
     at https://www.redhat.com/apps/support/
 for help.

[    34.280] (EE)
[    34.284] Server terminated with error (1). Closing log file.

I tried following the steps I found here: https://access.redhat.com/solutions/54937 with limited success. I'm now able to get the console up on the screen by pressing ctrl+alt+f2 (I couldn't before), but Xorg is still terminating in the same way.

I appreciate any help or advice anyone can give. I've hit the wall and I'm not sure how to proceed.

Thanks,

Mike

I tried the same solution (https://access.redhat.com/solutions/54937) with a different video card and monitor and found that it worked.
