Module Options
==============

Special configuration for smifb is usually unnecessary. There are a few
options, however.


From the command line, pass options to modprobe
modprobe smifb.ko lvds=1 width=1024 height=768

Or modify options on the fly at /sys/module/smifb/parameters directory 
change the parameter in place, and save the file.


Or for permanent option, create file like /etc/modprobe.d/smifb.conf with text
options smifb lvds=1 width=1024 height=768
