This is, I believe, a moot point. Saying that all boards have a PCI slot
doesn't mean that a user/developer wants to or has any intention of
using it. Think of situations where an embedded board is dropped into a
specialized case and sold as a project, for instance, the msntv2. The
board inside (rca rm4100) does have a PCI "slot", but no header, and the
case is designed such that pci cards are not meant to be used. In such a
case, there's no reason to include the rom emulator, increasing the size
(if ever so slightly), nor a reason to search for a video option rom,
increasing the boot time, if there is no rom to run.

BTW, thanks for getting back to this Luc, I know you're busy with the
new job. I apologize for the rather scalding response your patch has
had, these are the types of responses to patches this community does not
need, because we will scare away very experienced and good developers.

I think that we need a 3rd option, something like
CONFIG_NATIVE_VGA_INIT, to do what you want and skip the video option
rom search. I think that would make everyone happy ;)
