Subject: Make compilation of KMS parts optional

Configure with --enable-kms to enable the KMS parts.  With this option, the driver will
include both traditional (fbdev-based) and KMS drivers, and will choose between the two
at runtime depending on the kernel.  Without this option, the driver will be exactly as
the traditional driver.
