Comment 68 for bug 431812

It seems like three questions need to be answered:
 * What is the root cause?
 * When will it be fixed?
 * What are the workarounds in the meantime?

For workarounds: this bug is specific to certain Intel graphics chipsets, right? If the list of bad chipsets can be determined, then the installer/updater could "blacklist" those and automatically add the i915.modeset=0 to the grub configuration if necessary -- correct? That's probably not as great of a solution as actually fixing the problem, but at least it would make these offending computers usable without "user hacking".
