Драйвер nvidia

Debian. Собрал 2.6.31

Собираю двайвер NVIDIA-Linux-x86-173.14.20
хидеры стоят. gcc-4.1 и 4.3
модуль собирается без ошибок, но потом говорит что

ERROR: Unable to load the kernel module 'nvidia.ko'. This happens most
frequently when this kernel module was built against the wrong or
improperly configured kernel sources, with a version of gcc that differs
from the one used to build the target kernel, or if a driver such as
rivafb/nvidiafb is present and prevents the NVIDIA kernel module from
obtaining ownership of the NVIDIA graphics device(s).

Please see the log entries 'Kernel module load error' and 'Kernel
messages' at the end of the file '/var/log/nvidia-installer.log' for
more information.

помнится была лакая же чушь при каком то из обновлений ядра, но тогда оно как то быстро исправилось покупкой ATI (я кстати радовался - все ставилось и работало). А сейчас надо именно на nvidia запустить. Карта старая, это последняя рабочая версия драйвера. 173.14.18 вообще не собирается под 2.6.31

попробовал залезть на nv (3d не надо) - так оно вообще тупо виснет. Даже в логах тихо....
видяха работает - ядро 2.6.28 с nvidia без проблем. собирается и запускается.
