koreader.log from my PocketBook Basic 2 (614):

PocketBook framebuffer info
framebuffer finfo pitc  600
framebuffer finfo size  487424
framebuffer finfo pann  1       1
framebuffer vinfo xres  600     600
framebuffer vinfo yres  800     800
framebuffer vinfo offs  0       0
# initializing for device PocketBook
# framebuffer resolution: {
        ["h"] = 800,
        ["w"] = 600

I *think* that the Mini (515) uses the same framebuffer as the Basic 2, since the resolution is the same.
