I presume that without this change it was able to detect the appropriate
resolution of the connected monitor, but not of the LCD?

If so, this change effectively breaks that autodetection and forces
everything to the 800x600 display which is arguably very low-resolution
by today's standards. Why should this be the default? When you refer to
"the kit", what exactly are you referring to?

Also, is this a discussion you have already had with Tom? I don't want
to contradict what he has said regarding this BSP.
