It really goes in the right way from +1 to +4. But the detected screen height might be larger than actual one so that the application crashes before pitch size goes right.

Could you also screen shot with these changes?
Code:
elseif vinfo.bits_per_pixel == 8 then
            self.bb = BB.new(vinfo.xres, vinfo.yres/2, BB.TYPE_BB8, self.data, finfo.line_length + 5)

Code:
elseif vinfo.bits_per_pixel == 8 then
            self.bb = BB.new(vinfo.xres, vinfo.yres/2, BB.TYPE_BB8, self.data, finfo.line_length + 8)
else
which only use the first half height of the screen for test and increases pitch size from finfo.line_length + 5 to finfo.line_length + 8. I expect a sane half screen in one of the four trials.

And could you also print some basic info of the framebuffer at line 40 like this:
Code:
print("pitch size", finfo.line_length)
print("framebuffer size", finfo.smem_len)
print("framebuffer width", vinfo.xres)
print("framebuffer height", vinfo.yres)
