Looking at the code, I'm a little confused how it's supposed to work.
AFAICT, unless there's a DMI match, then the driver will only load
ifthe boot code sets VIDEO_TYPE_EFI, but nothing sets that.

grub should be setting that.

It looks like grub-fedora (the git version, anyway) has a function
set_kernel_params that tries to do this.  Peter, the git tree claims
that you maintain it.  Are there any experiments you'd like me to do?
(Dumping boot_params, perhaps?)

It's a bug in grub.  If I have a splashimage then efifb works.  If I
don't, then efifb doesn't.  If I don't hear anything back soon, I'll
file a bug against Fedora.

FWIW, efifb seems really slow.
