This is puzzling me

After installing F7 on a multiboot machine I tried to get hardware acceleration for my ATI X800 pro using radeon and fglrx drivers and failed to find a stable setup.

On subsequently booting back into one of my other OSes, FC6, the fglrx driver was no longer working in that! (Even though it was fine before). No amount of reinstalling drivers, reconfiguring xorg.conf would help upon many reboots.

So I decided to see if hardware acceleration was working in windowsxp, so booted that up and all was fine.

Then I rebooted back into FC6 and to my surprise that was now working too, I had my fglrx hardware acceleration back!

So my question is, can the radeon and/or fglrx drivers change some hardware settings on the card that the windowsxp ati driver is able to reset. Or is there another explanation for how it got fixed?

The reboot probably fixed it - I'm guessing you're using the Livna drivers as they reconfigure to your stored settings every boot up.

Long story short, that's basically the reason the drivers now require livna-config-display - Scripts detect your current configuration while DRI and fglrx is enabled. On bootdown DRI and the fglrx driver gets disabled to prevent problems, and when you start up the settings are set to their original state.
