I had to gave up with VESA.
Before all the changes (feb./mar. 2010) it was working perfectly with 
Now I have to use MODE_30, because any other higher resolution isn't working 
or it's crashing the machine, as I've reported yet.
I would like to add that yesterday, I left  twice my pc running CURRENT turned 
on while doing other things. And both time on my return it was dead. Not even 
replying to ping.
I had to set blanktime="NO" in /etc/rc.conf. I'm not sure if the problem has 
been introduced recently.
Did you noticed that too?
