wait voodoo? I really hope you do not mean the one for the galaxy s.
If it is the one from galaxy s no, no we cannot use it. What that voodoo does is changes the system memory to ext4 and some other sound and color fixes specific to the super amoled screen on those devices and speaker (for voodoo sound you can use dpsManager and color should not be needed). The reason it works on the galaxy s devices is that they use a much slower memory. I believe gingerbread by default uses ext4(do not quote me on that as I am not 100%sure just heard that some places) and for certain on some roms ext4 is default such as tun4f1sh's bulletproof miui to name one but are on much more. If this is not the voodoo you are looking for I just typed this out for nothing.
PS. I probably missed something here but just so you know desire z has nowhere near the same amount of lag as the galaxy s (i know i came from one never going back)
