Re: Modules "bitmap", "pcidata" not found
Please resinstall X server by loging as a root and typing:
nvidia 1.0-87XX drivers are a bit old. Try to use newer ones, but in Mandriva case drivers prepared by PLF(penguin liberation front).
I don't really think this is related to nvidia, please post your problem on Mandriva's corresponding forums or on #mandirva channel on freenode.
