I will now install the imu_drotek branch on a different directory and check it tomorrow at work. About the mag, mine works like a charm with those signs, checked with a gps and a traditional compass (all other in the airframe set to 1) and the imu positioned with the solder pad row facing back and the ic side (mag,mpu,baro) looking up.

 x = (int16_t) ((drotek_hmc5883l.buf[0] << 8) | drotek_hmc5883l.buf[1]);
 z = (int16_t) ((drotek_hmc5883l.buf[2] << 8) | drotek_hmc5883l.buf[3]);
 y = (int16_t) ((drotek_hmc5883l.buf[4] << 8) | drotek_hmc5883l.buf[5]);

 VECT3_ASSIGN(imu.mag_unscaled, x, -y, -z);

Did you already have a chance to test the imu_drotek branch?
You should be able to have a rather empty imu section (except mag calib,
body_to_imu and accel neutrals if you want).
