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.

That's expected, though I admit it's not the best thing ever. We're currently
working on not needing that bootloader at all any more, in favor of grub2,
which doesn't have this limitation.

FWIW, efifb seems really slow.

It's a non-accelerated console.  Of course it's slow.
