Maybe you are rather interested in these dmesg lines:
Linux agpgart interface v0.102
agpgart: suspend/resume problematic: resume with 3D/DRI active may lockup X.Org
on some chipset/BIOS combos (see DEBUG_AGP_PM in intel-agp.c)
agpgart: Detected an Intel G33 Chipset.
agpgart: Detected 8192K stolen memory.
agpgart: AGP aperture is 256M @ 0xd0000000
[drm] Initialized drm 1.1.0 20060810
ACPI: PCI Interrupt 0000:00:02.0[A] -> GSI 16 (level, low) -> IRQ 16
[drm] Initialized i915 1.6.0 20060119 on minor 0
...
set status page addr 0x00033000
agpgart: pg_start == 0x000005ff,intel_private.gtt_entries == 0x00000800
agpgart: Trying to insert into local/stolen memory

So the problem is, that X passes too low start.
