I found the below post to the XFREE86 Dev list. I'm disappointed since I have
been waiting the better part of a year for a new XFREE version that might fix my
Mobility M6 LY sync problems. If I understand the patch it changes the dot
clock frequency slightly. Any chance of getting this fix into 9.1 final.

Thanks,
I've committed your fix to the CVS.

description:
Computer is HP XT375 laptop with ATI Mobility LY M6 graphics chip. Mandrake
9.1 Beta 3 correctly identifies the chip and uses Radeon driver, defaults to
LCD monitor 1027X768 (also correct). There are two distinct problems:
1. Laptop monitor will not sync reliably. Has horizontal lines about 50% of
the time when X starts. Can be worked around by alternating Ctrl-Alt-Fx and
Ctrl-Alt-F6 (switch between a terminal session and X) until it syncs. Once
synced it will remain so until logging out/in or restarting.
2. On shutdown, when X stops a blue color band is displayed at the bottom of
the screen and the machine hangs.
Also, X works fine if the VESA driver is selected, shutdown works as well
without a problem.
Also Windows XP works fine using a resolution of 1024x768.
