Hi, I have a radeon 9250 card in my desktop (9200 pro, rv280) and I got an error on starting the xserver. I changed options in my xorg.conf and found out that the error only appears if I leave this line in: AGPFastWrite "On" Starting the x-server the card is shut down and there is no way to resume it. I have to reboot the machine. Without this line everyting works. I don't think that this is very important as you don't have to need this option but I don't think that this behaviour is intented. I'll attach the xorg.log and my lspci.

It's pretty much impossible to get working proprely, which is why it's disabled by default. You can try the code if you like, but, well, you've seen the results. :)
I did not file this bug because I want to enable AGPFastWrite, I file it because I think that any option which does not work should be disabled or ignored instead of leaving the system unusable. Or is this impossible, too?
Well, it does actually work for some people. Is the documentation in the man page not enough of a warning? At some point, when people are enabling options that explicitly mention being unsupported, not to mention not the default, we can't really stop them ... 'Enable AGP fast writes. Enabling this is frequently the cause of instability. Used only when the DRI is enabled. If you enable this option you will get *NO* support from developers.'
