Currently it is like vga=sm712fb:0x301 but if i change it to use fb_get_mode() then the boot parameters will change to vga=sm712fb:640x480@...8 , and that is why I am hesitating. But it will be more conventional to what all framebuffer drivers follows.

Hm...  That's a good question.

I suspect we should just go with fb_get_mode() and do it quickly.  This
driver is so new in the kernel that there are no users to get upset.
