OK, I figure the first line is about my RAM (512MB), the second the
aperture size I set in the bios (32MB) and the third my graphics card
memory (128MB).

This is what lspci says about my card:

02:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon
9200 PRO] (rev 01) (prog-if 00 [VGA])
        Subsystem: Connect Components Ltd Unknown device 2801
        Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 11
        Memory at d0000000 (32-bit, prefetchable) [size=256M]
        I/O ports at d000 [size=256]
        Memory at e3000000 (32-bit, non-prefetchable) [size=64K]
        [virtual] Expansion ROM at e2000000 [disabled] [size=128K]
        Capabilities: [58] AGP version 3.0
        Capabilities: [50] Power Management version 2

Does the line "Memory at d0000000 (32-bit, prefetchable) [size=256M]"
suggest that the card has 256MB memory? Because it really only got
128MB. Could this lead to the mtrr overlaps?
