Subject: [PATCH] set correct mclk/xclk values for aty in ibook
Date: Mon, 1 Nov 2004 16:47:23 +0100 [thread overview]
Message-ID: <20041101154723.GA14379@suse.de> (raw)
In-Reply-To: <20041101141622.GA14335@suse.de>
The first iBook needs special mclk/xclk values, or the screen will show
only garbage. A patch like this went into 2.4.23. It stopped working
after 2.6.10-rc1.
