    _______________________________________________________

Details:

Please consider the following:
Currently (legacy and new) grub forces the 2.02 protocol cmd_line_ptr to point
to the same memory area of the old protocol.

The result is that the limitation of the old protocol to a 256 bytes
command-line is inherit by the new protocol.

Please consider changing this behavior so that new protocol can receive more
than 256 bytes.

if (lh->version >= 0x0202)
-  lh->cmd_line_ptr = linux_data_real_addr + LINUX_CL_OFFSET;
+  lh->cmd_line_ptr = fixup (arg);
