Taking Gordon's code as a template, I suppose it would look something like the code below. I pulled the init sequence from u8g_dev_st7567_pi13264.c and the define statements from u8g.h.
NOTE: The code block rendering engine turns hash marks into links. In the define statements below you'll have to remove all the forward slashes.
// I grabbed these define statements from u8g.h in the u8glib library
// using this command "grep -ir U8G_ESC_* utility/u8g.h"
