0038 Choose this option if you have a system that has "Intel Graphics
0039 Media Accelerator" or "HD Graphics" integrated graphics,
0040 including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
0041 G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
0042 Core i5, Core i7 as well as Atom CPUs with integrated graphics.

0044 This driver is used by the Intel driver in X.org 6.8 and
0045 XFree86 4.4 and above. It replaces the older i830 module that
0046 supported a subset of the hardware in older X.org releases.
0047
0048 Note that the older i810/i815 chipsets require the use of the
0049 i810 driver instead, and the Atom z5xx series has an entirely
0050 different implementation.
0051
0052 If "M" is selected, the module will be called i915.

0058 This is the default value for the i915.force_probe module
0059 parameter. Using the module parameter overrides this option.
0060
0061 Force probe the driver for new Intel graphics devices that are
0062 recognized but not properly supported by this kernel version. It is
0063 recommended to upgrade to a kernel version with proper support as soon
0064 as it is available.
0065
0066 Use "" to disable force probe. If in doubt, use this.
0067
0068 Use "<pci-id>[,<pci-id>,...]" to force probe the driver for listed
0069 devices. For example, "4500" or "4500,4571".
0070
0071 Use "*" to force probe the driver for all known devices.
