My video-driver is "xf86-video-intel 2.3.2", and "X.Org X Server 1.4.2", my distribution is Archlinux. The patch's size is calculated with the dmesg from kernel-2.6.27. My lap-top computer work now, but I'm not sure that, So is there any specification about it or any suggestion, I'm glad to do some test on it. > > > > > and dmesg will show as below: > > > -->>-- > > > [drm] Initialized drm 1.1.0 20060810 > > > pci 0000:00:02.0: power state changed by ACPI to D0 > > > pci 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 > > > pci 0000:00:02.0: setting latency timer to 64 > > > [drm] Initialized i915 1.6.0 20060119 on minor 0 > > > pci 0000:00:02.0: pg_start == 0x00001f7f, intel_private.gtt_entries == 0x00001fff > > > pci 0000:00:02.0: trying to insert into local/stolen memory > > > --<<-- > > > > > > Then, I change file "drivers/char/agp/intel-agp.c" as this: > > > -->>-- > > > --diff --git a/drivers/char/agp/intel-agp.c b/drivers/char/agp/intel-agp.c > > > index 9cf6e9b..e681f75 100644 > > > --- a/drivers/char/agp/intel-agp.c > > > +++ b/drivers/char/agp/intel-agp.c > > > @@ -528,7 +528,8 @@ static void intel_i830_init_gtt_entries(void) > > > * stolen, ignore it in stolen gtt entries counting.
