video driver problems on set top box board

I am working ST set top box board and I need help to resolve some problems. if you 're working on set top box or you have experience with them these are more detailed informations:

I am using a set top box board : STB442 based on STi7109 chip. I use STAPI (drivers provided by ST) with STlinux kernell. I have some problems with a module (named mme_host) which must be inserted with arguments (insmod mme_host.ko transport0=<arguments_to_be_used>). This operation causes the following error :
insmod: error inserting '/home/bakhaled/modules/mme/mme_host.ko': -1 Operation not permitted
I tried to insert the module without arguments (insmod mme_host.ko) and this was successful. But when I try to run a test program for video , after inserting that mme module without arguments, the system crash down. (don't execute console commands).
Has any one experienced this type of problems?
Have you any solutions ?
