The same things happens for me with my X800XL (R430), something seems to go wrong with ati's R4XX-cards. The vga=xx solution works, but it's not perfect because it gives me another problem; the same kind of kernel panics when I leave X when using the fglrx driver (logout, ctrl-alt-f1 to get to terminal etc). This does _not_ happen if I disable splash and don't pass a "vga=..." kernel option. So I have: splash + no "vga=" = crash splash + "vga=" + fglrx = working, but crash on logout etc no splash + "vga=" = same as above no splash, no "vga=" + fglrx = working fine. Not sure if they are connected, but both problems cause the same kind of nasty kernel panics when you are trying to use the framebuffer...
