Radeonfb Xpress 200M RC410 support patch
From: Sellout Bessie
Date: Mon Sep 17 2007 - 05:31:40 EST
Ok, notthing special, and this is my first pqatch so forgive me if my method is off, however the following makes
radeonfb work ith the 200m Xpress RC410. In my tests it was terribly unstable and would freeze until I set a refresh rate in the kernel argument to 75.
e.g video=radeonfb:1280x800@75
Now it is rock solid.
Please CC me as well as I am not on the list...
