This check doesn't make sense, it will always be true.

Reminds me that I have some pending work to make vga ram size
configurable which I should finish and repost ...

Current state pushed to http://www.kraxel.org/cgit/qemu/log/?h=vga.1

It probably makes sense to base this on top.

Maybe also rename this to vgamem_mb for consistency with standard vga.
