I cannot get the xf86-video-siliconmotion driver to work correctly with my Siliconmotion LynxEM+ SM712 (rev 0). The module is successfully loaded into Xorg, but the rendering of 2D objects was simply unacceptably slow. I can only resolve this issue by making a rule in /etc/X11/xorg.conf.d/ in which EXA acceleration is enabled in conjunction with the LynxEM. I specified various options that are known to resolve graphical issues with the "Lemote Yeelong" netbook and I copied the correct modelines and sync rates from a normal Xorg session without any rules applied. The result is a nicely 2D-accelerated Xorg, but there are lots of garbled horizontal lines flying across the display. The card is capable of 24-bit colour depth and I tried to use 16 and 8-bit as well. There is no distortion in 8-bit colour depth(?). I extensively tweaked the Xorg.conf rule for days and I cannot conclude if the added configuration is at fault, or whether the driver has a bug.
After some research I learned that most issues with this card are related to exceeding VRAM usage and that its known to segfault Xorg on Debian based distributions. However, the driver is loaded correctly and does not segfault.

Bumping with an update, the Xorg acceleration method called "EXA" does speed things up, and at the same time is ultimately responsible for all the garble (no other options or vsync/hsync timers are involved). The LynxEM+ is a rather slow card with a maximum of 24-bit colour dept, however changing it to 16 or 8 barely speeds up anything. All the issues are somewhat similiar to the xf86-video-trident driver. The only option I have left is to use the legacy Accelmethod XAA used by XFree86. This extension is still delivered by distributors like Ubuntu (libxaa.so). The new question is, where do I find and install it for Arch? And out of curiosity, how does EXA cause the garble?
EDIT: grabbing libxaa.so from xorg-xserver-core from ubuntu yields:
(EE) SMI: Failed to load module "xaa" (module requirements mismatch, 0)
