After working with Colin Watson, using VMware Workstation as a
reproducer, we found that vesafb was not getting loaded. You can
experiment with this by replacing 'quiet --' with 'BOOT_DEBUG=3', then
blindly entering 'modprobe vesafb'.

This regression is almost surely due to the modularization of vesafb
(CONFIG_FB_VESA=m) which prevents adverse graphics interaction with
Plymouth on the desktop. One possible workaround is to revert this
change for the -server flavour, e.g., CONFIG_FB_VESA=y. The desktop
install does not use the 'vga=788' boot option.
