framebuffer refresh rate and geometry

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Hello

When the kernel initialize a framebuffer, the signal ouput changes a bit 
fro mwhat is inherited from the BIOS. I face the situation where the 
display looses the signal, and I suspect this is related to the refresh
rate.

Where is it set? I found no kernel option about it. 

This is with intelfb on amd64.
