Using the "How to use framebuffer X server" article with a vga=791 and installing Xorgs-7.6.tcz extension before starting X (startx), Tiny Core 4.1 looks good and the installation works very well after rebooting. Thus, the Xorgs-7.6 video driver for this difficult Neomagic video display works much better than the Xvesa extension. In the future, I will upgrade to the current version of Tiny Core Linux.
