Still, this is not always enough. I cursed many times when the x86
emulation on Alpha machines was not capable of executing the hacks
some vendors put in their option roms, which prevents video or
booting from scsi from working.

This is also a matter of effort. I'd definitely prefer having the
graphics hardware vendors write initialization firmware for their
device than to do that myself for every vendor whose graphics card
I happen to use. In clusters this would not matter. It's all the same
hardware anyways, and no video is needed. But for many other
applications it's really useful.
