Display problem on IBM A21p

[frank wang]

I have burned a livecd of fedora 7 and the cd works fine with my new
desktop. However, when I try to run the livecd on my IBM A21p thinkpad
with 512MB RAM. The display is screwed up. It has two displays, each
takes about half screen. I have the same problem with ubuntu 7.0.
Since I hope fedora 7 will fix this problem and I wait until the
release of fedaora. The display card is ATI mobility 128.

Could anyone tell me how can I fix this problem? Without the display,
I could not install fedora on this computer.

Thanks

Frank
