This set of two patches add support for the framebuffer of the Samsung S3C2410 ARM SoC. This driver was started about one year ago and is now used on iPAQ h1930/h1940, Acer n30 and probably other s3c2410-based machines I'm not aware of. I've also heard yesterday that it's working also on iPAQ rx3715/rx3115 (s3c2440-based machines).
