The above shouldn't be necessary.

And it should have been documented in Documentation/kernel-parameters.txt.

And "fbsize=N" would be a lot more conventional than "fbsize:N"

I suspect that the formulation you have here will not permit "fbsize:128k",
whereas "fbsize=128k" or "gxfb.fbsize=128k" should work.  Needs checking.

Because the module_param() already makes fbsize available on the kernel
boot command line via gxfb.fbsize=42 (or something similar).
