Me and Alex talked to a BIOS guys yesterday exactly about that, a

How about reading DCE registers?
I can try and consult with DAL on this.
At least the second patch somehow addresses the memory waste concern,
the reservation will be very transient, during late init the BO will get
Sure, I don't think anybody's concerned about that. My concerns are:
* In the cases where we still only reserve 256K, there will likely still
be artifacts during driver initialization.
* 32M might still not be enough in some cases, e.g. 5K / 8K displays.
I see your point, as I said above, will again try to find out if there
is still a way to know the BIOS FB size.
P.S. Please don't top-post.
