As far as I can see, (GRUB_LINUX_CL_END_OFFSET-GRUB_LINUX_CL_OFFSET) = 0xff
And argv[] is truncated to this amount.
I believe you guys can do this much better than I can. Only needed action to
be taken is to set cmd_line_ptr on >=2.02 protocol to untruncated null
terminated string.
So construct a string out of argv[], then copy/truncate this to the old
command-line 256 buffer for compatibility.
Grub is much more complex than this one...
This is opened from jul-2007!!!
