--- Comment #28 from Patrick Rudolph <siro@xxxxxxxxxxxxx> ---
I found another issue:
I tested KDE Neon Live DVD. It does not boot because the code checks additional
window attributes:

mov dx,[es:edi+2] ; win A/B attributes
and dx,707h
cmp dl,7
jz set_mode_50 ; win A is rw

It depends on VBE_WINDOW_ATTRIBUTE_RELOCATABLE.
The comment indicates that it needs only VBE_WINDOW_ATTRIBUTE_READABLE and
VBE_WINDOW_ATTRIBUTE_WRITEABLE.

Is the attribute VBE_WINDOW_ATTRIBUTE_RELOCATABLE required ?

It shows a splash screen and boots if I just advertise
VBE_WINDOW_ATTRIBUTE_RELOCATABLE without checking what's it's good for.
