You enable the driver in the eCos configuration tool. eCos does not do 
dynamic linking of kernel modules - it's anticipated that you know what 
drivers your hardware will use so you include them specifically.

You can use ioctl as well, but there might be a more specific interface. If 
it's your own driver, just add whatever function you want! Unlike Linux, 
eCos has everything right there directly - just call the function directly.
