Ah, I did that previously, it gave me a black screen and locked up.
I'll get the log from that tomorrow and send it here.

Note, we are switching from EFI framebuffer mode, so could that be an

And, just to make it fun, this laptop also has an nvidia chip in it, but
someone else is working on getting the nouveau driver working on it, I
was trying to stay away from that mess :)
