This start to be offtopic with the bug title, because now fglrx installs 
with the 2.6.38 kernel,
so it's possible that Alberto prefers to close it and open a new one.

Latest tries I've been done with fglrx 8.840 in a up-to-date natty with 
intel/Ati hybrid:

#aticonfig --px-dgpu
PowerXpress: Discrete GPU is selected (High-Performance mode), please 
restart Xserver for changes to take effect!
PowerXpress: Fail to switch GLX link file, please check whether driver 
install correctly
#aticonfig --px-igpu
PowerXpress: Integrated GPU is selected (Power-Saving mode), please 
restart Xserver for changes to take effect!
PowerXpress: Fail to switch GLX link file, please check whether driver 
install correctly

I've seen that when trying to change cards aticonfig expects
/usr/lib/xorg/modules/extensions/libglx.so to be a link
By changing it to a link, and trying again, you discover the names of 
the linked files in each mode, and they are (supposed to be):

/usr/lib/xorg/modules/extensions/FGL.renamed.libglx.so for the original 
libglx.so mesa file with --px-igpu and
/usr/lib/xorg/modules/extensions/fglrx/fglrx-libglx.so for the fglrx 
libglx.so with --px-dgpu
and copying/linking these files you can avoid the Fail in aticonfig.


But X keeps complaining with:
