Corrections in red:
Not exactly....
I apologise, I was reading for context, and make sense from within a wealth of
22 years of Nix experience.
The link is describing difficulty with v41/ABI drivers within Virtualbox
booting into X via PCLinuxOS. When you build a virtualbox client, the xdrivers
modules are created also; sometimes when one installs Virtualbox (and/or Xen),
they decide to run their first system in a virtual under the OS, which is then
described as primary in the grub configuration via the new kernel that was
built during install (which might cause an X and kernel module mismatch). For
instance under Redhat/XEN this is usually what is called a PAE kernel. You,
after installing Virtualbox, verified that you are still running the same
kernel from grub.conf? You can also look at the file creation date for the
kernel that is indicated to boot first into the grub configuration.
Post installation of Virtualbox, your Xorg logs say what?
If I remember correctly Xorg was whining we needed a couple of video modules?
Irregardless of whether you are now running in a VirtualBox or not:
a) boot fails to go to X
b) you can't startx
Solutions:
1) You can try to boot into your system and reconfigure your X drivers via
command line?
First try this:
# sudo Xconfigurator
You can try to configure your monitor and video card for X via this utility.
Might work, it's worth a try...[but not highly probable].
2) Update/upgrade your system, although this might have been what caused it.
There are some major differences between the way that X uses kernel drivers for
video cards in recent versions.

sudo apt-get update
sudo apt-get upgrade
3) Kernel modules and X drivers
Your Xorg errors talked about two drivers:
module ABI major version (1) doesn't match server's version (2)
failed to load module "v41" (module requirement mismatch,0)
# sudo dpkg-reconfigure -phigh xserver-xorg
4) Revert your failed system If these questions do not make sense, and you
can't either fix the driver errors or roll back the changes made adding
virtualbox source, it would be easiest for you to just rebuild. Download a new
ISO from distrowatch (or a new OS) and burn it to CD (or DVD if you have that
luxury) carefully selecting the i386/686 versions and drop the hammer on this
failed learning project, and go on to bigger and better things!
After you rebuild your shiny new system, keep your BUILD DVD/CD, so you can use
it to boot emergency for trouble/rebuild. Always keep a record of all steps
that are done, (especially updates, etc. and test between upgrade installation
steps) for packaging the issues for others.
5) If all this fails, take your box back to the InstallFesters and/or call one
of us.
