+xf86-video-openchrome-0.3.0
+
+This is the first official openchrome driver release.
+(http://www.openchrome.org)
+
+SUPPORTED CHIPSETS :
+--------------------
+- CLE266 (VT3122)
+- KM400/P4M800 (VT3205)
+- K8M800 (VT3204)
+- PM800/PM880/CN400 (VT3259)
+- VM800/CN700/P4M800Pro (VT3314)
+- CX700 (VT3324)
+- P4M890 (VT3327)
+- K8M890 (VT3336)
+- P4M900/VN896 (VT3364)
+
+
+SUPPORTED FEATURES :
+--------------------
+- Free modesetting for Unichrome and Unichrome Pro chipset.
+- VBE modesetting for everything not natively supported.
+- TV out support.
+- EXA acceleration.
+- Hardware MPEG2 acceleration.
+
+
+IMPORTANT NOTE :
+----------------
+- The driver name is now 'openchrome', that's what you need to use in your xorg
+ conf now. The XvMC libraries have also been renamed to libchromeXvMC.so and
+ libchromeXvMCPro.so
+
+
+KNOWN BUGS/LIMITATIONS :
+------------------------
+* Laptop panel
+- Laptop's panels for anything but CLE266 and KM400/P4M800 are only supported
+ thru VBE calls.
+- Xv is not working on laptop's panel for VM800/CN700/P4M800PRO. It is however
+ working on VGA.
+- Virtual terminal is broken on some laptop's panel. Use a vesa framebuffer to
+ workaround that (append vga=791 to your kernel command line for example).
+
+* XvMC
+- The hardware MPEG4 acceleration that is present on some chipsets is not
+ implemented.
+- No XvMC support for CX700 (new unsupported engine)
+- No XvMC support for K8M890, P4M890 and P4M900/VN896 (need to get dri working
+ for them first)
+
+* TV output
+- TV modes are hardcoded and must be choosen inside a list depending on the TV
+ encoder.
+- Outputs are dependant on each other and will use the lesser common
+ denominator. If you're using both VGA/LCD output and TV output, the VGA/LCD
+ output will be limited by the TV encoder (720x576@50Hz for example).
+ In other words, there is no dual screen support.
+
+* Misc.
+- Add-on and integrated TMDS encoders are not supported, except true VBE.
+
+
+Please note that 3D acceleration is provided by Mesa (http://mesa3d.org) and is
+not directly related to openchrome.
