[CentOS] Installer stopped short

Hi,

I just tried to install a CentOS 5 desktop on very recent hardware, an 
Acer desktop machine. The installer stopped short very early. I gave 
Ubuntu 8.04 a shot, and it installed without a problem. Now what can I 
do about this?

Is there a way to use some "enhanced" kernel (like the centos.plus 
kernel) to perform the install? I guess what's missing there is a 
specific driver for something (SATA drive? Processor?).

Any suggestions?
