I have checked with Hardy Heron [and Zenwalk with kernel 2.6.25]. I notice these messages in addition to the PCI messages
PCI: Bridge: 0000:00:01.0
IO window: 9000-9fff
MEM window: b0100000-b01fffff
PREFETCH window: c0000000-cfffffff
PCI: Bridge: 0000:00:04.0
IO window: disabled.
MEM window: disabled.
PREFETCH window: disabled.
PCI: Bridge: 0000:00:05.0

MEM window: disabled.
PREFETCH window: disabled.
PCI: Bridge: 0000:00:06.0
IO window: disabled.
MEM window: disabled.
PREFETCH window: disabled.
PCI: Bridge: 0000:00:07.0
IO window: disabled.

PREFETCH window: disabled.
Sadly, on an ACER 5051AWXMi [my Laptop :-( ], these correspond to the PCI Bridges for video.
00:00.0 Host bridge: ATI Technologies Inc RS480 Host Bridge (rev 10)
00:01.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge
00:04.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge
00:05.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge
00:06.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge
00:07.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge
checking dmesg reveals:
ACPI: PCI Interrupt 0000:01:05.0[A] -> GSI 17 (level, low) -> IRQ 21
[fglrx] GART Table is not in FRAME_BUFFER range
glxgears will report a score around 1700fps but enabling compositing will drag the system. I believe that the root cause of this issue also causes the laptop to underperform when running 3D applications.
I do not know if this is relevant, but I cannot seem to get my display to work in 32bit depth , though 24 seems just fine. Could this be the result of the same issue?

why you guys haven't made the problem go away. Try compiling form
source.
