AutoConfigure support for older Geodes

Here is a simpler patch that would apply to the X server 1.4 in Hardy. Potential candidate for an SRU?

Here's a revised patch that applies to both X server 1.6.3 (karmic) and 1.6.0 (jaunty).

As pointed out by Julien Cristau, the fall back to "amd" on GX2 and LX can be safely removed for servers 1.6.0 and 1.6.3, since both GX2 and LX have fully migrated to the -geode driver.

However, in principle, GX2 could still fall back to "nsc" as needed, thus we'd be left with:

  case 0x1022:
      if (dev->device_id == 0x2081) {
  /* AMD Geode LX */
   driverList[0] = "geode";
      }
      break;
 /* Geode products acquired by AMD still carrying an NSC vendor_id */
 case 0x100B:
     if (dev->device_id == 0x0030) {
  /* NSC Geode GX2 */
  driverList[0] = "geode";
  driverList[1] = "nsc";
     } else
  /* NSC Geode SC */
  driverList[0] = "nsc";
     break;

Test packages for Karmic and Jaunty made with the above patch are available via my PPA.

Here's an updated patch for the X server 1.6 series.

Here's an updated patch for X server 1.4.1 from Hardy.

To recap:

1) The 1.6.x patch can be immediately applied to X server 1.6.3 in Karmic. Enjoy!

2) The 1.6.x patch can be applied to X server 1.6.0 in Jaunty as well, but only after cherry-picked commits from Geode 2.11.4.1 have been applied to Geode 2.11.1-1 in Jaunty.

3) The 1.4.1 patch can be applied to X server 1.4.1 in Hardy only after cherry-picked commits from Geode 2.11.4.1 have been applied to Geode 2.9.0-1ubuntu2.5 in Hardy. This might prove to be a lot harder to accomplish than items 1 and 2 , because of the sheer number of recent #ifdef in Geode that were added to support newer X servers that we'll need to weed through before we can spot essential fixes and verify that they apply cleanly on 2.9.0 without introducing any regression. The difficulty level might be similar to the 2.8.0 to 2.9.0 jump we made right after Hardy was released. From this perspective, resorting to a straightforward backport of 2.11.4.1 might prove to be a more practical solution.

PS: anyone who wishes to test this can use the packages in my PPA (Geode 2.11.4.1 backports and patched X servers for Hardy, Jaunty, Karmic) as a reference.

X server 1.6.x patch committed to upstream xorg/xserver git as 842b7a47d583a7729099de3031ae20977dddf774.

This bug was fixed in the package xorg-server - 2:1.6.3-1ubuntu6

    older geode cards. Cherrypick from upstream.

Thank you for this Karmic release!

Moving on to the SRU for older releases. Please stay tuned.

AMD Geode LX800 is not detected properly in UNR KK (9.10) On my netbook the resolution should be 800x480, but it detects only 4:3 resolutions (800x600, 640x480, 320x240 etc).

Stanislav, what you're reporting is not related to this bug. Besides, it has already been reported as bug #433142.
