So I've decided to switch to KMS on this kernel with
00:02.0 VGA compatible controller [0300]: Intel Corporation 82G33/G31
Express Integrated Graphics Controller [8086:29c2] (rev 02) (prog-if 00
[VGA controller])
        Subsystem: Intel Corporation 82G33/G31 Express Integrated
Graphics Controller [8086:29c2]
        Flags: bus master, fast devsel, latency 0, IRQ 26
        Memory at ffa80000 (32-bit, non-prefetchable) [size=512K]
        I/O ports at ec00 [size=8]
        Memory at d0000000 (32-bit, prefetchable) [size=256M]
        Memory at ff900000 (32-bit, non-prefetchable) [size=1M]
        Expansion ROM at <unassigned> [disabled]
        Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit-
        Capabilities: [d0] Power Management version 2
        Kernel driver in use: i915


with this X driver:
(II) Module intel: vendor="X.Org Foundation"
        compiled for 1.7.4, module version = 2.10.0
        Module class: X.Org Video Driver
        ABI class: X.Org Video Driver, version 6.0


on X.Org X Server 1.7.4 and after some time I get:
(WW) intel(0): i830_uxa_prepare_access: gtt bo map failed: Input/output
error
(EE) intel(0): Failed to submit batch buffer, expect rendering
corruption or even a frozen display: Input/output er
ror.

and kernel says:
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
render error detected, EIR: 0x00000000
[drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5
(awaiting 153151 at 153150)
[drm:i915_gem_execbuffer] *ERROR* i915_gem_do_execbuffer returns -5


>From <debugfs>/dri/0/i915_wedged, the GPU is wedged.
