VGA in uClinux--DE2 board

Hello,

I just finished writing a user-space driver for controling the VGA on the DE2 board through uClinux. Its actually quite small. Could any one give reasons (advantages) for having the driver as a kernel module instead of a user-space application. I need to access the VGA from Java which is running on top of uClinux thus I made it user space.

Any help (concrete reasons) would be appreciated.

regards,
