     40	  including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
     41	  G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
     42	  Core i5, Core i7 as well as Atom CPUs with integrated graphics.
     43
     44	  This driver is used by the Intel driver in X.org 6.8 and
     45	  XFree86 4.4 and above. It replaces the older i830 module that
     46	  supported a subset of the hardware in older X.org releases.
     47
     48	  Note that the older i810/i815 chipsets require the use of the
     49	  i810 driver instead, and the Atom z5xx series has an entirely
     50	  different implementation.
     51
     52	  If "M" is selected, the module will be called i915.

     60
     61	  Force probe the driver for new Intel graphics devices that are
     62	  recognized but not properly supported by this kernel version. It is
     63	  recommended to upgrade to a kernel version with proper support as soon
     64	  as it is available.
     65
     66	  Use "" to disable force probe. If in doubt, use this.
     67
     68	  Use "<pci-id>[,<pci-id>,...]" to force probe the driver for listed
     69	  devices. For example, "4500" or "4500,4571".
