You don't need to use the module parameters for that. You can allocate
memory for the framebuffer by echoing

echo mem-amount > /sys/class/graphics/fb?/size

Note that the overlays connected to that framebuffer need to be
disabled.

Also, in your example below, you don't even use fb1, so I don't see much
point in allocating 2M for it.
