Here's three more logs, with the v3 L2 cache patch (but I don't see any of it's relevant printk's -- might have need/forgot to do a make clean).
warm boot fails.
cold1 boot gets to SeaBIOS menu along but at kernel execution, reboot is executed -- sorry, forgot I had quiet param enabled!
cold2 boot reboots during bios init and fails.
(I've had more success using coreboots video option rom execution versus Seabios. I will try with Seabios (stable & svn) video option rom next on this board, but it usually fails.)
