SMP i810 systems were practically nonexistent and the configuration was not officially supported by Intel at the time when Pentium-III was common. With this change, it is still possible to build a distribution kernel that has support for SMP and includes the i810 driver without the BKL. As a precaution, check for the theoretical SMP case at run time and refuse to load the driver. We also need to disable CONFIG_PREEMPT builds for this driver.

Choose this option if you want kernel modesetting enabled by default,

and you have a new enough userspace to support this. Running old

userspaces with this enabled will cause pain. Note that this causes

|
the driver to bind to PCI devices, which precludes loading things
