Not sure this is really meant to be, but it seems the efifb is
initialized because grub passes this VGA type to the kernel. When I
uncomment the line in /etc/default/grub that sets GRUB_TERMINAL=console,
then the efifb driver is not loaded. There is a early error message that
video mode could not be set but at least this results in the cirrus
driver loading all the time.

graphics fail to initialise correctly, in kvm with cirrus graphics
(after LUKS install)
Status in “cryptsetup” package in Ubuntu:
Status in “grub2” package in Ubuntu:
Status in “linux” package in Ubuntu:
Status in “plymouth” package in Ubuntu:
Status in “ubiquity” package in Ubuntu:
reproducible with ubiquity or alternate installer in KVM virtual machine:
1) select lvm + encrypted instalation
it fails to boot, in a way that I get "no video mode activated" and I cannot type the password in to unlock the drive.
As a workaround, I had to:
1) force reboot machine
2) then grub options come up
3) select recovery mode
4) then I can enter the password using text interface
5) resume normal boot
Disabling splash, brings up text interface to unlock the drive &
allows to boot.
