My test computer has an old nVidia card in it.
Mageia 3 alpha installs quite happily on it, but
it won't boot to a GUI. It gives error messages
about nouveau, even though the modules has been
deleted and XFdrake run to try "nv" then "vesa".
BTW there is also an EDID check sum error from
the monitor which could be confusing things.
There is a repeat of 8 lines of hex data and
[drm] nouveau 0000:01:00.0: DDC responded, but no EDID for VGA-1
