help with latest ATI catalyst driver on fedora 15

[Leonardo]

hello all i would like to know how to build an rpm package for ati
driver on fedora 15

i've found this topic on the internet[1] but it caused strange video
issues (i.e. superior bar with strange colors) on gnome3

if no alternative rather the pointed one is available, maybe i get kde
for a while, bu would be nice to get the full performance on the nice
gnome shell.

thanks in advance.
