suse 11.1 dowsn't start - problem with driver ATI

Hi, yesterday I installed ATI driver on my suse 11.1, but then I can’t start suse…when I try to boot, after it loading, it appears a black screen, and I can’t do nothing. But I can’t start suse in safamode, becouse the result is the same.
I tried to start suse only with terminal, but I didn’t succeed…

I use suse 11.1 32 bit with kde 3.5.x
