Modules "bitmap", "pcidata" not found
New installation of Mandriva 2007 (kernel 2.6.17-5mdv) on MSI L730 laptop with Geforce Go 6100 card. First boot after installation gave blank screen, subsequent boots go to command line. After startx command, reports that the two modules bitmap and pcidata cannot be found, so aborts. (Annoying because a perfectly capable nvidia driver was loaded for the installation phase!). Judging by contents of /usr/lib/xorg/modules... directories, version 8774 seems to be installed.
No GUI available, so where to I go/what do I do now?
