Details:
Some emulation software (VirtualBox in my case) are slow at emulating VGA
modes that use a planar memory layout.
The memory layout information is supposed to be part of the VBE mode
information.
Is it possible to include this information in the information vbeinfo outputs
about a given mode?
If it was included it would be faster to figure out which mode would work
fast in an virtual machine. It would of course also be beneficial if the
default gfxmode was changed to one that doesn't use a planar memory layout
(only if possible), as they seem quite hard to emulate in a fast way.
