Subject: 3.5-rc6 fb hw inteldrmfb

On a computer of someone else, on which today I tried to 
install 3.5-rc6 (what on my computer and on an HP pavillon 
laptop runs without problem - on the laptop however needs 
ircpoll otherwhise don't find the harddisk), few seconds 
after start booting it sticks and don't continue longer 
(reboot not possible with Ctr-Alt-C but only pressing the 
reboot button), the last message is:   "conflicting fb hw 
usage inteldrmfb vs VESA VGA - removing generic driver" 
        then the cursor stops blinking, and the computer 
sticks.
With 3.4 the same computer runs since weeks without 
problems.  So, that's a regression.

Inspection of syslog, messages, debug don't show anything 
from this boot, it seems before the crash it hasn't nor 
time to log something.

Below is the lspci of that computer.
