No more increase permgen size setting?

[LezChap]

I have a user of my mod pack having an out of permgen memory error. There used to be an option in the launcher to increase permgen size...however, I can't seem to find it anymore. Is it gone? Is there a back way of achieving a higher permgen size setting?
