Good evening (UTC+0200),

First, I must say that I don't understand 99% of the technical details of this
discussion. I'm only the bug reporter. ;-)

There's one thing about my computer that may affect, or maybe cause this bug.
There's no need to make possibly harmful change to the kernel only to fix it on
a few machines with buggy bioses.

My computer is an Asus M51Se laptop with an HD3470 graphic card. This card is
an "hypermemory" one with 256MB dedicated RAM and up to 1GB with shared
memory. The problem is that I don't know how the computer assigns main memory
to the card. There is nothing in the bios to indicate the amount of shared
memory (and Asus did not answer my questions).

Once again, I'm not an expert, so if this details are not important, please
forgive me.

Sincerely,

Yannick
