OK. The not really correctly working device (so far) is the graphics card ---- snip ---- 01:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT 330M] (rev a2) ---- snip ---- as I get only some standard VESA resolution (800x600 or so - but there is a full-hd-screen on it) with X. I'm in the process of playing around with that ("nv vs nouveau driver" or "is it a system-config-display issue") and writing something in the Fedora-12 bugzilla eventually - if only to see where the real problem lies. > You mention the "name_count maxed" messages, and I think you meant > they go away when you use "pci=use_crs".

I (also) thought similar - I also just googled for the line (and didn't find anything useful, probably not enough googled) and just wondered why it was gone. So I take is as "not related".
