That bug always existed, simplefb is just the first driver to hit it
(vesafb/efifb didn't use resources).

Heh, the bug didn't "exist" because no other grabbed the resource
before.  The way the cirrus driver allocates the resource is no bug,
per se.  But the proper resource takeover is missing.

I'm aware of the issue but as a
workaround you can simply disable CONFIG_X86_SYSFB. That restores the
old behavior.

Yes, but CONFIG_X86_SYSFB breaks things as of now.  Shouldn't it be
mentioned or give some kconfig hints instead of silently giving a
broken output, if any quick fix isn't possible?

Indeed. That's called a "regression" in distro/allmodconfig kernels.
