Sorry, I should have extracted the solution and made it big and bold (I forgot your system just got downgraded at an Installfest, and you are PTSD stuck!)

This will fix her:
Reinstall Virtualbox Guest Additions from the terminal:

http://www.informit.com/articles/article.aspx?p=1271263&seqNum=3


Install VirtualBox as described Part 1 and Part 2 of "Sun VirtualBox (xVM): A Virtualization Environment for Linux" article.
Of course, if you had Xterm you could just do:


Next: Virtualbox Console > Devices > Install Guest Additions
There is a script somewhere hereabouts:
cd /media/VBOXADDITIONS_2.0.6_39755 [directory name will vary with the version]
sudo sh ./VBoxLinuxAdditions-x86.run [or -x64 if running a 64-bit guest]

Other stuff probably not related:

Just FYI, the problem is that you upgraded to a new kernel, so you had to recompile or reinstall your graphic drivers smile.gif.

Updates between versions are sometimes a lottery!

Let's look at how we must package a problem for the PLUG:  We follow these steps (dumping into email):

1) What is it (versions, etc)? 
2) What is she whining about (Linux like any good partner will tell you very clearly what is the issue)?

[Ignore my installation references for Ubuntu's Virtualbox (they are just info); but possibly an update to the ABI module or v41 module were done during the installation?]

Check the file creation date for your Grub at /here/boot/grub/menu.lst
Check to verify what she is currently booting there - look for backup files and diff.

Discussion:  http://www.pclinuxos.com/index.php?option=com_smf&Itemid=26&topic=54523.0

We might logically research the exact Xorg errors for these, spoze?

3) Research our error for known solutions:

module ABI major version (1) doesn't match server's version (2)
failed to load module "v41" (module requirement mismatch,0)

4) The Zen of Troubleshooting, "The error is the problem"

Looks like you have a kernel module mismatch grasshopper.
