SLES 9 and IA-64

I was trying to install a IA64 server with SLES 9. When I used, "Installation", "Installation Safe" or "Manual". It froze once Yast started and sometimes it came up with the message saying something about " ... 96MB of video memory is necessary or X-server did not ..." Are there arguments I can pass to the kernel so the installation does NOT freeze? Thanks, LDB
