Lucid-10.04-1 VirtualBox-v4.0.2 kernel-2.6.38

Following Question #144799 created 2011-02-10

I got a working solution to my problem by posting it to "wiki.ubuntu.com/BugSquad".
I got the following answer :
QUOTE
as for your situation, it should be:

sudo ln -s /usr/src/linux-headers-2.6.38-1-generic/include/generated/autoconf.h /usr/src/linux-headers-2.6.38-1-generic/include/linux/

then compile the module again:

sudo service vboxdrv setup

I found another solution in the virtualbox forum but it asks to change several paths in the source code and I think this one is more easy.

(sorry for my poor English)

Even if it is dirty it works perfectly - after I have replaced 2.6.38-1 by my current kernel number 2.6.38-3.
I eventually add that this kernel looks very promising : very fast execution and a working WiFi ! added to that now a working VirtualBox : wonderful.
