Default 180.06 report (some improvements)

First... I'll say that a rather large improvement --- that the adapter now detects the AC line --- is very appreciated. However, there are some rather debilitating regressions.

The most noticable problem is that it can't detect that both my desktop display and my integrated display (in my laptop) are 1920x1200. If there is no configuration in the xorg.conf regarding resolution, it will choose 1024x768. If I use nvidia-settings, it wants to add a "metamodes" line consisting of "DFP1: 1920x1200 +0+0" ... in which case the display comes up in 1280x1024 mode.

I've tried several different configurations --- including using the internal display. The note in the log file is similar to:

(--) NVIDIA(0): Connected display device(s) on GeForce 8700M GT at PCI:3:0:0:
(--) NVIDIA(0): Seiko (DFP-0)
(--) NVIDIA(0): DELL 2405FPW (DFP-1)
(--) NVIDIA(0): Seiko (DFP-0): 330.0 MHz maximum pixel clock
(--) NVIDIA(0): Seiko (DFP-0): Internal Dual Link LVDS
(--) NVIDIA(0): DELL 2405FPW (DFP-1): 330.0 MHz maximum pixel clock
(--) NVIDIA(0): DELL 2405FPW (DFP-1): Internal Dual Link TMDS
(II) NVIDIA(0): Display Device found referenced in MetaMode: DFP-0
(II) NVIDIA(0): Assigned Display Device: DFP-0
(WW) NVIDIA(0): No valid modes for "DFP-0:1920x1200"; removing.
(WW) NVIDIA(0): Unable to validate any modes; falling back to the default mode
(WW) NVIDIA(0): "nvidia-auto-select".
(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0): "nvidia-auto-select"
(II) NVIDIA(0): Virtual screen size determined to be 1024 x 768
(--) NVIDIA(0): DPI set to (70, 84); computed from "UseEdidDpi" X config
(--) NVIDIA(0): option
(==) NVIDIA(0): Enabling 32-bit ARGB GLX visuals.

each time.

I've attached an nvidia-bug-report.log file to help with debugging this --- although I don't see it saying much about the EDID read from the flat panels.

Additionally, if the metamodes line is in the xorg.conf, then nvidia-settings will not even offer 1920x1200 as an option.

Interestingly, the external flat panel sees the video signal as 1920x1200 the whole time (ie: the panel is not doing the scaling).

It's worth noting that we still have 100% interrupts on one of the two CPUs. I'm also forced to use -vo gl or -vo gl2 on mplayer (meaning many other movie players don't work).

But on the plus side, it would appear that solid window moving is now good (no noticeable lag).
