screen full of garbage on Xorg start

[Adam Pribyl <pribyl lowlevel cz>]

Fedora 10 tries now to have a nice boot with plymouth and KMS, 
however at least for me on nvidia and intel, when Xorg is started, I 
either see screen full of garbage, or old video memory content, until GDM 
starts with this nice fade in effect. But few seconds with this 
garbage in between plymouth and and gdm start is really disturbing..

How to avoid it?
