The vesa driver has that already, in a sense:
depths = VBEFindSupportedDepths(pVesa->pVbe, pVesa->vbeInfo, &flags24,
/* Preferred order for default depth selection. */
if (depths & V_DEPTH_24)
defaultDepth = 24;
else if (depths & V_DEPTH_16)
defaultDepth = 16;
else if (depths & V_DEPTH_15)
defaultDepth = 15;
/* ... */
So we should do the right thing, if the BIOS is polite enough to not lie
to us. Of course, it could be lying.
Having the _server_ retry successively smaller depths is a fair idea,
but really hard to implement given the way driver setup works right now,
and fixing it sort of requires fixing all the drivers in the same pass.
