In SuSE 9.0 Insmod is not working

Hi, In SuSE 9.0, if I want to load the driver using 'insmod', it results in a following error: powerfull:~ # insmod tg3 insmod: can't read 'tg3': No such file or directory But If I provide a full path it works fine. But will not allow one to pass parameters to the driver. Any help in this appreciated. thanks in advance, Anil
