it's the M7 vs the M22, I have this is X11 startup:

(--) PCI:*(1:0:0) ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500] rev 0, Mem @ 0xe0000000/27, 0xc0100000/16, I/O @ 0x3000/8
(--) Chipset ATI Radeon Mobility M7 LW (AGP) found
(--) RADEON(0): Chipset: "ATI Radeon Mobility M7 LW (AGP)" (ChipID = 0x4c57)

One of the things I was thinking of trying is to toggle
the BIOS setting PCI/AGP for the LCD display, maybe that will make
a difference. I never understood why that is configurable in a
laptop, either it has AGP or it doesn't you'd think.
