There are VESA standard timings for those modes. Specifically 1024x768 at 60, 70, 75 and 86Hz, and 1280x1024 at 75Hz. There are also standard timings for 1280x1024 at 60 and 85Hz. Is your monitor a CRT or TFT? Can you extract the EDID from it?

I have to add the following to the boot command when installing :- nomodeset ati.modeset=0 radeon.modeset=0 and then I can get to the desktop with a complete install. Once there, I then have to install a proprietary driver.
Thanks for that, I'll make a note for future reference. However, from the research I've done ATI's current proprietary driver releases do not support my (apparently ancient) card, so I've rolled back to 12.04 which is working fine except for giving me the "signal out of range" error during boot. I can live with that, at least for now.
Sometimes it turns out that installing Linux can be as hard work as installing Windows!
(And... why is there no VESA standard above 800x600? Minimal 1024x768 and 1280x1024 VESA compatibility across all graphics cards would go a long way to making this problem go away!)
