Remove radeonfb, the version in the Linux kernel is much better.

-/*
- *	drivers/video/radeonfb.c
- *	framebuffer driver for ATI Radeon chipset video boards
- *
- *	Copyright 2000	Ani Joshi <ajoshi@unixbox.com>
- *
- *
- *	ChangeLog:
- *	2000-08-03	initial version 0.0.1
- *	2000-09-10	more bug fixes, public release 0.0.5
- *	2001-02-19	mode bug fixes, 0.0.7
- *	2001-07-05	fixed scrolling issues, engine initialization,
- *			and minor mode tweaking, 0.0.9
- *
- *	2001-09-07	Radeon VE support
- *	2001-09-10	Radeon VE QZ support by Nick Kurshev <nickols_k@mail.ru>
- *			(limitations: on dualhead Radeons (VE, M6, M7)
- *			 driver works only on second head (DVI port).
- *			 TVout is not supported too. M6 & M7 chips
- *			 currently are not supported. Driver has a lot
- *			 of other bugs. Probably they can be solved by
- *			 importing XFree86 code, which has ATI's support).,
- *			 0.0.11
- *	2001-09-13	merge Ani Joshi radeonfb-0.1.0:
- *			console switching fixes, blanking fixes,
- *			0.1.0-ve.0
- *	2001-09-18	Radeon VE, M6 support (by Nick Kurshev <nickols_k@mail.ru>),
- *			Fixed bug of rom bios detection on VE (by NK),
- *                      Minor code cleanup (by NK),
- *			Enable CRT port on VE (by NK),
- *			Disable SURFACE_CNTL because mplayer doesn't work
- *			propertly (by NK)
- *			0.1.0-ve.1
- *	2001-09-25	MTRR support (by NK)
- *			0.1.0-ve.2
- *	2001-12-17	sync with 0.1.1:
- *			PanelYRes - module parameter
- *			- rage theatre (please see gatos.sf.net)
- *			- buggy tvout detection (need radeon_i2c)
- *			+ better powerpc support
- *			+ better radeon2 pll computing
- *			* Note: my stuff still work better for me than official
- *			  linux driver :(
- *	Special thanks to ATI DevRel team for their hardware donations.
- *
- * LIMITATIONS: on dualhead Radeons (VE, M6, M7) driver doesn't work in
- * dual monitor configuration. TVout is not supported too.
- * Probably these problems can be solved by importing XFree86 code, which
- * has ATI's support.
- *
- * Mini-HOWTO: This driver doesn't accept any options. It only switches your
- * video card to graphics mode. Standard way to change video modes and other
- * video attributes is using 'fbset' utility.
- * Sample:
- * 
- * #!/bin/sh
- * fbset -fb /dev/fb0 -xres 640 -yres 480 -depth 32 -vxres 640 -vyres 480 -left 70 -right 50 -upper 70 -lower 70 -laced false -pixclock 39767
