Bug#805178: inteldrmfb: unable to set console resolution

[Camaleón <noelamac@gmail.com>]

Source: linux
Version: 3.2.68-1
Severity: normal

I'm trying to set console resolution on a machine with the following 
ingredients:

- Intel 915G chipset
- KMS enabled (by default) with intel driver module
- inteldrmfb loaded
- Eizo display (21" wide, 1680x1050, VGA output)
- vbeinfo run from GRUB2 console allows 1920x1200, 1600x1200, 1280x1024, 
1024x768, 800x600 and 640x480
- /etc/default/grub.conf has:

GRUB_GFXMODE=1600x1200,1680x1050,1280x1024,1024x768,800x600,640x480
GRUB_GFXPAYLOAD_LINUX=keep

I'm unable to get the desired/native resolution (1680x1050) in tty 
consoles when system boots. Before getting into udev messages, 
resolution seems to be momentary set but it changes afterwards and 
console text becomes big again.

Note that inside X system (XFCE and LightDM) the resolution is manually 
configured by means of xorg.conf file and works as expected, is just 
consoles that I'm unable to set.

Greetings,
