[CentOS] What is the "not supported" hardware?

When the installer complains that it has detected unsupported hardware, is there any way to tell just what it didn't like? Following the URL in the message just ends up at the RHEL Hardware Certification page, which isn't much help. The installer seemed quite willing to continue with the installation, and poking around from the shell VT I didn't find anything that didn't seem to be working. I also didn't see anything relevant in any of the message VTs.

As it turns out this isn't a big deal for me, since this was the CentOS 6.5 installer and there was no such warning from the 6.6 installer. I'm just wondering how I might go about tracking that down,
