This is getting a bit off-topic (of the original thread).
For LKMs, I can envision one of two solutions.
1) Each LKM includes some sort of info (PCI IDs, etc.) indicating what the=
driver (may) support. So if we find unconfigured PCI IDs, we know what=20
LKMs to try.
2) We compile in "Module" support, which would be a stub driver that=20
matches, then on attach calls out for the right driver to be loaded.
So you're right, we don't want to try _every_ driver. But we can figure=20
out how not to. :-)
