* About margins; i'm sure that they are to be the bit between HDisplay and
* HBlankStart, HBlankEnd and HTotal, VDisplay and VBlankStart, VBlankEnd and
* VTotal, where the overscan colour is shown. FB seems to call _all_ blanking
* outside sync "margin" for some reason. Since we prefer seeing proper
* blanking instead of the overscan colour, and since the Crtc* values will
* probably get altered after us, we will disable margins altogether. With
* these calculations, Margins will plainly expand H/VDisplay, and we don't
