A frame buffer bug was introduced into the ps3-linux.git tree
on Aug 17th.  It was fixed Dec 17th.  Any kernels with this bug
will not boot on firmware 2.10.  The bug only effects systems with
firmware 2.10 (and later).  The bug is not hit with older firmware.

This is the fix:

The kernel sources used for CELL-Linux-CL_20071023-ADDON has this bug.

This older version of kboot should work:

You'll most likely need to update your installed (second stage)
kernel also.

Sorry for any inconvenience.
