+
+This is a submodule to access linux framebuffer devices.
+It is supported to work as helper module (like vgahw)
+for the chipset drivers. There are functions for
+saving/restoring/setting video modes, set palette entries,
+and a few more helper functions. Some of them can be
+hooked directly into ScrnInfoRec.
+
+In ../drivers/fbdev is a "chipset" driver. It is a simple,
+non-accelerated and hardware-independent driver which works
+on top of this fbdevhw submodule.

+.SH NAME
+fbdevhw \- os-specific submodule for framebuffer device access
+.SH DESCRIPTION
+.B fbdevhw
+provides functions for talking to a framebuffer device. It is
+os-specific. It is a submodule used by other video drivers.
+A
+.B fbdevhw
+module is currently available for linux framebuffer devices.
+.PP
+fbdev(__drivermansuffix__) is a non-accelerated driver which runs on top of the
+fbdevhw module. fbdevhw can be used by other drivers too, this
+is usually activated with `Option "UseFBDev"' in the device section.
+.SH "SEE ALSO"
+__xservername__(__appmansuffix__), __xconfigfile__(__filemansuffix__),
+xorgconfig(__appmansuffix__), Xserver(__appmansuffix__), X(__miscmansuffix__),
+fbdev(__drivermansuffix__)
+.SH AUTHORS
+Authors include: Gerd Knorr, based on the XF68_FBDev Server code
+(Martin Schaller, Geert Uytterhoeven).
