Yes, thanks. Though I assumed »best results« would mean, that when using
coreboot for loading the VGA Option ROM, that it might decrease
performance or something like that and not that Linux does not find the
ROM at all. If that is a known issue, a note should be added to the
Kconfig description or if coreboot is chosen as a target, then the
Option ROM option should be enabled automatically, right? If yes, please
say so and I am going to try to come up with a patch.


Thanks,

Paul
