    Disable shadow by default on known-virtual GPUs
    
    Device memory is the same domain as host memory, in this case, so the
    shadow just introduces more memcpy.

    Refuse to run on UEFI machines running older kernels
    
    Prior to kernel v3.12, the efi framebuffer driver was named "efifb".
    This cause problem on RHEL 7 as the base kernel is 3.10.
    
    "efi-framebuffer.0" was added by commit 2645e0aa for that reason
    (don't run on UEFI machine).
    The change from "efifb" to "efi-framebuffer" was done with commit
    e6816a8 in the kernel

    Try harder to avoid 24bpp
    
    We're preferring depth 24 even if that means 24bpp. Newer servers don't
    support 24bpp anymore, and even for old servers it's suboptimal. Change
    the heuristic to only try 24bpp if the alternative is pseudocolor.
