This modifies the segment at 0x0 so that it contains enough of a fake Extended BIOS Data Area at addresses 0x40e and 0x413 that Xen can correctly locate its trampoline code. Since custom Xen is no longer required, we can remove the module, the patches and all of the references to it in the board definition files.
