Loading 16207 LCD driver

I'm using the 16207 LCD on my DE2 board for a project, and it works when tested through the Nios IDE. I include the option for it in the uClinux menuconfig, but I don't think the driver is being loaded. It doesn't come up at boot time, or in /dev, or in lsmod, or any other place I can think of. Is there any way I can load it manually?

Thanks for your help.

Edit: it doesn't even seem like any object code is being built for it. Does it depend on any options besides "[*] Nios 16207 LCD device support" ?

    Check the Makefile and Kconfig in the dir of the driver. maybe something missing.

    Thanks! The makefile in that directory was missing an entry for the driver. It now generates object code, but I&#39;ll have to wait till tomorrow to see if it works.
