Subject: Patch for radeon framebuffer
Date: Sat, 15 Mar 2003 14:24:08 +0100 [thread overview]
Message-ID: <20030315142408.7d3bc3c0.hanno@gmx.de> (raw)
The patch below has been around for ages now.
It is needed on some radeon mobility cards, because they report 0 for
their video-ram-size.
Without the patch, the radeonfb will not work.
Can you include this in the next kernel release?
