Sorry for completely forgetting about this... (for so long)

I've tried your patch now against 3.1, and it seems to not help.

Thanks.  Logs?  (If you can't get netconsole or a serial console
working, a photograph is fine.)

Not sure whether trying with 2.6.38 helps.
It "stopped" working within the very same kernel.

Not sure what you mean.  Are the quotation marks for emphasis, or do
you mean that when you replaced the mainboard it did not stop booting
in v2.6.38 but something else entirely?

As a reminder for forgetful people like me, the debugging patch in
question is at [1].
