/home # du -xhs .
183.7M .
Is there something I'm missing ? There is a discrepancy of roughly 1.2Gb!

Then why does du take longer to run, and why is df almost instantaneous? I was not making things up with my answer.

The /home is mounted on /dev/mmcblk0p2. It shows:
/home/user # cd /home
/home # df -h .

Hello! I had the same problem and I reflash bouth partitions and works.
First go to:
https://wiki.maemo.org/Updating_the_firmware
Download the firmware (RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin) and the eMMC VANILLA one (note that you have to install the old version - RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin).
Install the eMMC first and then the last combined firmware later.
Enjoy!
Pd: Don't forget to backup previusly... this will leave your N900 like out of the box
