Neither does my NT, it doesn't have /proc/eink_fb at all. I can't yet try the ioctl.
How do you get these? And is there a simple test program for the framebuffer update ioctl?

Even the old kindle has the "eips" command. "eips -i" shows information about the framebuffer. "eips -g" will display images on the screen. "eips <x> <y> 'text'" will display text.
What I have been doing to update the display (even in C programs) is "eips ''" (that is two single-quotes following eips).
As I understand it, there is a different ioctl call to use with the new kindles, but it did not work for me -- I plan to replace the system("eips ''"); calls with ioctl calls "some day"...
And eips even works on kindle 3 and kindle DX, so it is "more portable" than ioctl calls or /proc/. It is easy to use eips in scripts as well...
