These are some of the checks I made:

[root at belexeuli lcl]# urpmi kernel-headers
Package kernel-userspace-headers-3.3.8-2.mga2.x86_64 is already installed

[lcl at belexeuli ~]$ rpm -qa |grep nvidia
x11-driver-video-nvidia-current-295.71-1.mga2.nonfree
nvidia-current-doc-html-295.71-1.mga2.nonfree
nvidia-current-kernel-3.3.6-desktop-2.mga2-295.49-4.mga2.nonfree
dkms-nvidia-current-295.71-1.mga2.nonfree
nvidia-current-kernel-desktop-latest-295.71-1.mga2.nonfree
nvidia-current-kernel-3.3.8-desktop-2.mga2-295.71-1.mga2.nonfree

[lcl at belexeuli ~]$ rpm -qa kernel*
rpm: No match.

[root at belexeuli lcl]# urpmi kernel-desktop-devel
In order to satisfy the 
'kernel-desktop-devel-3.3.8-2.mga2|kernel-desktop-devel-3.3.8-1.mga2|kernel-desktop-devel-3.3.6-2.mga2|kernel-desktop-devel-3.3.8-2.mga2|kernel-desktop-devel-3.3.8-2.mga2|kernel-desktop-devel-3.3.8-2.mga2|kernel-desktop-devel-3.3.6-2.mga2|kernel-desktop-devel-3.3.8-1.mga2' 
dependency, one of the following packages is needed:
  1- kernel-desktop-devel-3.3.6-2.mga2-1-1.mga2.x86_64: The kernel-devel 
files for kernel-desktop-3.3.6-2.mga2 (to upgrade)
  2- kernel-desktop-devel-3.3.8-2.mga2-1-1.mga2.x86_64: The kernel-devel 
files for kernel-desktop-3.3.8-2.mga2 (to upgrade)
What is your choice? (1-2) 2
Package kernel-desktop-devel-3.3.8-2.mga2-1-1.mga2.x86_64 is already 
installed

Very puzzling.  Maybe something does need to be urpme'd as Doug suggested.
