19 * Some x86 clamshell design devices use portrait tablet screens and a display
20 * engine which cannot rotate in hardware, so we need to rotate the fbcon to
21 * compensate. Unfortunately these (cheap) devices also typically have quite
22 * generic DMI data, so we match on a combination of DMI data, screen resolution
23 * and a list of known BIOS dates to avoid false positives.
