The default > kernel configuration provides for 128M, but Randy found that: .../... it's a problem with ioremap of the framebuffer ? (which uses get_vm_area as well) or is there an actual vmalloc in there ? In radeonfb, I had to limit the amount of vram actually ioremap'd by the kernel because of that.
