I did not added file list to the static kernel config due to display
becoming blank after the driver initialization, which is very early
for the syscons setup.  Might be, since vt is functional, this may
be reconsidered.

Driver initialization was never tested when loaded from loader, I
have no idea how i915 starts up with interrupts still disabled.
