[Wine] Minecraft in Wine

[OakRaider4Life]

I'm currently running a Windows version of Minecraft in Wine (don't ask why...), and wanted to know if there was a way to configure the java virtual machine which is run in wine so as to run Minecraft in a ramdisk machine. I know if I was running a linux native version, I could use the command 

Code:

java -Xmx[Memory] -Xms[Memory] -jar [/path/to/minecraft]



What I would like to be able to do is configure my java VM in wine similarly... any tips?
