Dan,

unfortunately I had wrong information. S1D13305 is equivalent to SED1335
that is significantly
different from SED1355 (1335 does not provide a full bus interface
address/data) so the driver
Epson epson1355fb.c is not useful :-(
The main problem is that framebuffer memory is not accessible linearly like
a standard RAM. This means
that even graphical environment low-level routines (for example nano-x)
must be rewritten to manage
the read/write operations on framebuffer memory.
