New driver: s3d2xfb

Hello,

attached is a (completely unaccelerated) framebuffer driver for S3 Trio 
3D/2X video cards. This is currently for out-of-tree testing, not for 
merging (although the license doesn't prohibit merging). Reason: this is 
my first kernel driver, and it has been tested only with my video card 
so far.

Signed-off-by: Alexander E. Patrakov

What works:

This driver works on my old video card with 2.6.14-rc1-mm1 and 2.6.12.5 
kernels. Applications tested: fbcon, jfbterm (has red <-> blue glitch), 
mplayer (doesn't like DirectColor modes, "fbset -nonstd 1"), fbxine 
(works perfectly), Xorg's "fbdev" driver.

Known bugs:

The "rom" file in sysfs is unreadable
"Snow" in high-resolution modes (but the MS Certified Win98 driver just 
gives pixel corruption in the same modes)
YWRAP may or may not work with cards that have 8MB of video memory.

Please send testing reports, including the "it just works" ones. Be sure 
to include the kernel version, driver messages and "lspci -n" output.
