We have been in communication with Samsung BIOS engineers about this issue,
but have no ETA for a BIOS update at this time.

We can't say with certainty that there is no risk of trashing the firmware -
however, we have confirmed that the samsung-laptop module in the latest
12.04 daily images (as well as in the latest raring daily images) has been
rendered inert when booting under UEFI instead of under CSM, so there should
not be any bricked machines as a result of issues in *that* code. It is
*likely* that this was the root issue causing problems for all users but
once again, it's impossible to say with absolute certainty because we aren't
in possession of the machines in question.
