OK.

Clean os874 just connect to network and reboot.

df says that /dev/mtdblock0 is 1024MB, 699MB is used and 326 MB is available.
Removed dri and firmware (but usb8...bin) for parity with os2.
df says 354 MB is free.
dd /dev/urandom writes 344.3 MB before "No space left on device"
Clear the dd written files, reboot and start copying files from a USB stick. 
Nine (six of them the same as in os2) tag.gz and squashfs files.
I copied 356.6 MB before "No space left on device"

So it would appear ubifs takes ~60 MB more.

Hopefully from now on `df' will be more believable ;)
