Hi Jim Gettys,

Thank you so much. You already help me a lot and please don't worry about 
slackware. I don't think the problem was there but on fedora. That is why 
I try to find out where it is.

I know and test OLPC fedora versions and they have no problem on usb8xxx. 
But no problem appear did not means problem did not exist.
Problem did show in slackware 10.2 means problem exist.
Problem did not show in old BIOS did not means problem did not exist too.

It was useless for me to use full fedora OLPC source code because doing so 
I made repeated experiment that you and your friends already did and will 
find nothing new.

The problem is not exist in your lib/kernel/bin but exist outside that 
areas.

Please let me clearify my duty:

I am not talent in working to solve hardware problem under fedora 
environment.

My talent is to apply your products to make it easy to be used universally 
in sustainable manner.

So far, I found that amd driver you made cannot solve .swf problem.
And amd driver did work correctly on several versions of kernels and Xorg.

Your information did alredy help me much about building xorg because 
earlier it was impossible for me to make it small to contain in a small 
usb drive.

Different amd version may cause problems on your current work but did not 
cause problem on slackware. So, please don't worry on versions I used. The 
problem is not there.

If you forced me to use only fedora and follow exactly fedora did then you 
will get nothing from me. And that will be useless to OLPC too.
