Problems with LSM9DS0 I2C

I'm using a LSM9DS0 wired to communicate with I2C. The chip seems to recognize when its being addressed, ACKs bytes, responds to reads, etc. but the problem is it always sends the same byte back. For example: I attempt to configure the device through the following sequence:
0xD4 0x20 0x7F 0x04 0x08 0x00 0x40

where D4 is the gyro address and 20 is the starting register. I then perform a read of 5 bytes to ensure that the device is configured as I want it to be but receive only five instances of 0x40. The pattern seems to be that the last byte written to a register is simply repeated over and over by the chip. The only exception is when reading the WHO_AM_I registers which respond as expected.

Has anyone else had this problem or have any ideas as to what might be going wrong?
