    Looks like the same problem on a desktop:

    Mobo Asus A7V8X-X:

    Never tried this machine with kernel older than 2.6.2.
    FB VESA works fine. If i use ATI Radeon (does'n matter old or new) the screen
    goes dark until i start X. With the new driver i found in dmesg:

    [...]
    Kernel command line: root=/dev/hda1 vga=0x31a
    [...]
    PCI: Using ACPI for IRQ routing
    PCI: if you experience problems, try using option 'pci=noacpi' or even 'acpi=off'
    radeonfb: cannot map FB
    SBF: Simple Boot Flag extension found and enabled.
    SBF: Setting boot flags 0x1
    [....]


    Compile warnings with new driver:

    [...]

    drivers/video/aty/radeon_base.c:474: warning: `xtal' might be used uninitialized in this function
