BUGS
This driver does not provide any mechanism for access from user applica- tions. Its only use at this point is to provide a means for framebuffer device drivers to query monitor description data (EDID) using a special- ized in-kernel API. No support for sending control commands to display devices is provided. NetBSD 9.0 May 11, 2006 NetBSD 9.0
