Default 1080i Resolution unused by nvidia-auto-select on 60-inch HDTV, [ Sony KDS-R60XBR1 ]

Display: 60-inch rear projection 1080i, HDTV, Sony KDS-R60XBR1.

Card: GeForce 7900 GS, AGP 8X, DVI to HDMI.

Box: AMD64, Linux Kubuntu Edgy 6.10,

Kernel: 2.6.17-11 generic. Xorg 7.1.1. Nvidia 1.0-9755.

The graphics and platform are very stable. KDE runs a beautiful 32 bpp display with excellent 3D and 2D motion.

The panel's native resolution is 1080i, [ xorg EDID section snip: ]
Code:
(--) NVIDIA(0): --- EDID for SONY TV (DFP-0) ---(--) NVIDIA(0): Detailed Timings:
...
...
(--) NVIDIA(0):   1920 x 1080 @ 60 Hz
(--) NVIDIA(0):     Pixel Clock      : 74.25 MHz
(--) NVIDIA(0):     HRes, HSyncStart : 1920, 2008
(--) NVIDIA(0):     HSyncEnd, HTotal : 2052, 2200
(--) NVIDIA(0):     VRes, VSyncStart : 540, 542
(--) NVIDIA(0):     VSyncEnd, VTotal : 547, 562
(--) NVIDIA(0):     H/V Polarity     : +/+
(--) NVIDIA(0):     Extra            : Interlaced

The problem: 1080i (or other interlaced resolutions it seems) are unused, nvidia-auto-select will instead use:
Code:
(II) NVIDIA(0): Native backend timings for SONY TV (DFP-0):
(II) NVIDIA(0):   1280 x 720 @ 60 Hz
(II) NVIDIA(0):     Pixel Clock      : 74.25 MHz
(II) NVIDIA(0):     HRes, HSyncStart : 1280, 1390
(II) NVIDIA(0):     HSyncEnd, HTotal : 1430, 1650
(II) NVIDIA(0):     VRes, VSyncStart :  720,  725
(II) NVIDIA(0):     VSyncEnd, VTotal :  730,  750
(II) NVIDIA(0):     H/V Polarity     : +/+
(II) NVIDIA(0): 
(II) NVIDIA(0): 
(II) NVIDIA(0): --- Modes in ModePool for SONY TV (DFP-0) ---
(II) NVIDIA(0): "nvidia-auto-select" : 1280 x  720 @  60.0 Hz  (from: EDID)
(II) NVIDIA(0): "1280x720"           : 1280 x  720 @  60.0 Hz  (from: EDID)
(II) NVIDIA(0): "1280x720_60"        : 1280 x  720 @  60.0 Hz  (from: EDID)

1920x1080i worked perfectly on this same platform, display panel, using ATI Radeon 9600.

Bug report attached, Xorg.0.log attached [startx -- -logverbose 5], look forward to troubleshooting further and thank you for your assistance in advance.

Cheers,

Vinny.
