FX5200 TV-out@1024x576x25fps

[DonP]

Hello,
I was wondering if anyone has successfully got Xorg running the nvidia driver 1.0-6111 at 1024x576 at 25fps (PAL-I widescreen), interlaced or otherwise?
I've got 720x576 25 fps non-interlaced running fine but my TV is widescreen so I'd really like to run at 1024x576

Unfortunately everything I try returns errors like:
(II) NVIDIA(0): Not using mode "1024x576" (illegal horizontal timings)
(II) NVIDIA(0): Not using mode "1024x576_25.00" (illegal horizontal timings)
(II) NVIDIA(0): Not using mode "1024x576a" (hsync out of range)
(II) NVIDIA(0): Not using mode "1024x576b" (bad mode clock/interlace/doublescan)
(II) NVIDIA(0): Not using mode "1024x576d" (hsync out of range)

The lines I've tried look like this:

I'd be very grateful for example modelines.

TIA!
