Steve,
I have a few questions:
0) Does this reproduce with an official Redhat kernel?
1) Is there a Redhat bug open for the 1.03 SBIOS problem? I'd be curious whether the SLI problem persists with the 1.03 SBIOS (and an IDE drive, I guess).
2) What does the output from "lspci -vt" look like?
3) Do all the other SLI modes fail in a similar fashion?

Thanks,
Lonni

I have the same problem.. Don't really know how to do a bug report. I tried Auto, SFR, AFR and SLIAA and nothing worked. I just hang to a black screen right on X start. Looking at the Xorg.0.log shows that it happens right after the PCI bus is being probed. Oh well. Guess I can just throw one of these extra 7800s away
