[ubuntu-x] Testing legacy driver fix for Intel graphics

[Alexey Efremov]

Just tried to use legacy driver, but I can't boot with i915.modeset=0
set. gdm tries to load, fails and reloads again, fails again etc.
Without this line system loads fine. Testing the driver now (takes
~day to catch a new freeze usually, so can't tell right now if it
helped)

Ubuntu 10.04. My VGA controller details below:
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series
Chipset Integrated Graphics Controller (rev 07)
	Subsystem: Lenovo Device 20e4
	Flags: bus master, fast devsel, latency 0, IRQ 45
	Memory at f2000000 (64-bit, non-prefetchable) [size=4M]
	Memory at d0000000 (64-bit, prefetchable) [size=256M]
	I/O ports at 1800 [size=8]
	Capabilities: [90] Message Signalled Interrupts: Mask- 64bit- Queue=0/0 Enable+
	Capabilities: [d0] Power Management version 3
	Kernel driver in use: i915
	Kernel modules: i915

I tried to install Maverick backport (2.6.35-17) before, but it didn't
help. Upgrading driver to 2.11.0 too.
