No, I spelled out a list of projects, what would break, and how it would
break.

Again,

* Red Hat driver disks. The build process is unaware of the need to
bundle firmware. Any use with Fedora (or, later, RHEL) will result in a
non-working driver, for the simple reason that firmware is not copied
onto the image.

* Embedded projects like OpenWRT, that divide up kernel modules into
multiple packages. Since it's not just one big package, you have to
update each package's list of files to include the newly split-out
firmwares. Failure to do so results in a successful build set of
packages... of drivers that lack their firmware.

* Router and embedded system image builders like tomsrtbt, with similar
problem to RH driver disks: they simply do not know that a firmware
needs to be copied into the image, alongside the tg3 driver.

* Older userlands where, axiomatically, the mkinitrd and other firmware
fixes have not been made, and may never be made.

Yes, it is a matter of education.

Yes, it is a matter of fixes.

That does not change the fact that 2.6.27 will mean non-working drivers
for these situations, and there is a simple remedy for this entire class
of problems: retain ability to compile firmware into the module.

That does not change the fact that useful testers may be turned away
from 2.6.2[78] while waiting for Red Hat or OpenWRT or whomever to fix
their stuff.

Jeff
