1080i modes broken in 100.14.23 (and every other 100.x 9x.x version)

[Blammo]

Any 100.x version I can currently test is still broken with with EDID with interlaced modes. progressive modes work fine, but interlaced modes still show the top half of the screen only, doubled rows, so to speak.

Here's a "startx" with debug (attached, zipped) from 100.14.23 with the following options in the log:

(**) NVIDIA(0): Option "NvAGP" "3"
(**) NVIDIA(0): Option "ConnectedMonitor" "DFP-0"
(**) NVIDIA(0): Option "RenderAccel" "1"
(**) NVIDIA(0): Option "IgnoreDisplayDevices" "CRT"
(**) NVIDIA(0): Option "XvMCUsesTextures" "true"
(**) NVIDIA(0): Option "AllowGLXWithComposite" "true"
(**) NVIDIA(0): Option "ModeValidation" "AllowNon60hzDFPModes,NoVertRefreshCheck"
