When booting with OVMF+CSM, the first video mode that we ask for is mode 0x143. This doesn't seem to work; the qemu display window doesn't change size, and remains blank.
If the first thing we ask for is a *text* mode, then things work fine. This is arguably a bug, but I'm not about to go chasing it.
I should know never to say things like that; if I'm offended by something it's almost always a lie to say that I won't actually go and hunt it down. This patch is more minimal and highlights the actual problem. Not sure what *else* is missing...
