I just went through the same process, generating an XML file for a 1Gbit Micron part that wasn't otherwise available from Altera. I used the existing XML for MT47H64M8-3 from the preset_library.xml file to generate the same info for the MT47H64M16-3. It turns out that only 4-5 parameters were different.

If you copy/paste the <preset> </preset> section to a new file and then call it (for example) MT47H64M16.xml and then leave it in the same directory as preset_library.xml, it will show up in the Megawizard menu, as a selection.

Between the Micron datasheet and Micron's HDL simulation file (ddr2_parameters.vh....both available on the web), I was able to come up with all of the parameters needed for the XML file. It did take an hour or so, but now I should be good to go.
