+This code is dependant upon the direct frame buffer library. It requires
+that the file /dev/fb be present this means that the kernal level frame
+buffer driver must be loaded. In order to load the svga (vesa) frame buffer
+you must load it in grub.conf. This requires adding the following line to
+one of the boot kernels:
+
+kernel /vmlinuz-2.6.22.9-61.fc6 ro root=LABEL=/1 video=vesafb:ywrap,mtrr
+vga=788
+
+This fb driver is only activated at boot time and the settings can not be
+changed using fbset. You can also try loading the module as root if you know
+your cards maker.
