commit 4ed7d2ccb7684510ec5f7a8f7ef534bc6a3d55b2 upstream. Loongson MIPS netbooks use 1024x600 LCD panels, which is the original target platform of this driver, but nearly all old x86 laptops have 1024x768. Lighting 768 panels using 600's timings would partially garble the display. Since it's not possible to distinguish them reliably, we change the default to 768, but keep 600 as-is on MIPS. Further, earlier laptops, such as IBM Thinkpad 240X, has a 800x600 LCD panel, this driver would probably garbled those display. As we don't have one for testing, the original behavior of the driver is kept as-is, but the problem has been documented is the comments.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
