Question [Q] Changing the kernel command line on 2X?

Can anyone tell me how to change the command line passed to the kernel for the LG 2X?

It doesn't seem to be included in boot.img files like with other phones. I'd love to change mine to allocate less memory for the GPU and more for the GPU (I think I don't need 128MB for the GPU, a lot of Tegra devices have it set to 64MB).
