This one is trivial to fix, we don't need or want the vgahw module on MIPS.
Heck, the SM50x isn't even VGA compatible.

Yes and no. Some newer SiliconMotion chips do have VGA compatibility
goo, and if we were using VGA text mode on them then the vgahw module
would actually be useful. We don't though.

I'm going to fix that in the next few days.

have fun
