I met with same problem on my Pocketbook 912, and after some time I figured out how to solve it. BMP should be in indexed color mode and without compression. ImageMagick by default producing RLE compressed bmp.
For indexed palette I am using default logo image 1_st.912.bmp.

So if you have image with right resolution you can do this:

$ convert someimage.png
-background white
-alpha remove
-depth 8
-colors 256
-type grayscale
-remap 1_st.912.bmp
-dither FloydSteinberg
-compress none BMP3:outlogo.912.bmp

Here's another example, how I converted OpenBSD's puffy to pocketbook logo.

$ wget -O Puffy.gif www.openbsd.org/art/puffy/puf800X689.gif # download image
$ convert Puffy.gif
-background white -gravity center -extent 825x1200
-alpha remove -depth 8 -colors 256 -type grayscale
-remap 1_st.912.bmp -dither FloydSteinberg -compress none
BMP3:puffy.912.bmp

This command will resize canvas, center original image and convert it to supported by pocketbook bmp file. Note: since you have other resolution, you should change 825x1200 string to your device's resolution.
