One issue that showed up is that i915 isn't getting loaded by udev,
because /etc/modprobe.d/blacklist.conf contains:
# This directive blacklists all devices which are members of the display class.
# It has the main effect of preventing udev from autoloading the fb drivers.
# vendor, device, subsystem_vendor, subsystem_device, class, class, class
install pci:v*d*sv*sd*bc03sc*i* /bin/true
So right now it gets loaded by the initramfs if video=i915 is in the
kernel command line, or by X when it starts otherwise.
One possible way to fix this, I guess, would be to replace this
blacklist entry with a list of blacklisted fb drivers, to allow i915
(and later radeon and nouveau) being loaded automatically on boot. Is
this feasible? Are there other/better solutions?
Cheers,
Julien
