There may be something left behind: the kernel/initrd. I don't touch it yet. But it is easy to include. Kernel is replaced if enable ADB package is applied.
Also if you changed other partitions / contents like root filesystem partition, etc, then the recovery won't restore it. But these things should be unaltered, unless you messed them manually.
The only device specific thing is a serial that is stored in the boot sector if I remember correctly. This is not touched by sd recovery, nor by any root set.
A good thing after 1.04 sd recovery is to do a 1.04 firmware upgrade. This will replace the kernel with the stock kernel.
