There's a driver for the S3trio in 2.4, but still not ported to 2.6.  It is
also a non-x86 driver.

You can try looking at drivers/video/skeletonfb.c (preferably the one in
the latest mm tree, as I've made some changes to it).  You can first
write a driver with a static var (does not change modes on the fly) to
keep it simple.  Then slowly advance to a more complete driver.

vesafb is one of the simplest driver, which only supports the most
essential functionality.

You can always write to the list (fbdev-devel) whenever you're stuck :-)
