If you use extrabiomes XL savanna's, meadows and shrublands are also valid places to look for bauxite as they are sub-biomes of plains. I also believe savanna's double as also having rubies as well, basically it's a hybrid of plains and deserts. I can't recall atm if it does have bauxite for certain but I do know I've found rubies there.
There is no Biome which contains multiple kinds of diffrent Biomedependand Materials, just to clear that up.
I noticed you left out coalfuel in liquid form because a mod already did that. According to the mod author, he lost the files and is possibly not updating it... Seeing as its not currently updated, would it be possible to have liquid coalfuel from your mod, at the very least until the other author updates, if ever?
Even then, I won't add a Liquid for them. I try to avoid adding other Mods Liquids, as the Liquid Dictionary works another way than the OreDictionary.
I know it doesn't belong here, but guys, did the obfuscation change from 1.4.6 to 1.4.7? Do we need another update?
Lets hope it didnt change, as I'm not going to make a special update to 1.4.7, unless IC², Redpower, Thermal Expansion, Railcraft, Buildcraft and Forestry are updating to that.
@chunkLazurite: I forgot to add a Name to the ignored Names List, after changing it from blockLazurite to chunkLazurite.
