Yes, it is.  Otherwise it oopses as soon as something is printed on
/dev/tty<any>.  Quite early at boot with "console=tty1", otherwise as
soon as /sbin/getty starts on /dev/tty1.  Oh, and the reason is it
thinks it has an EGA card with 0 lines and 0 columns because we never
ran the real-mode boot code and thus SCREEN_INFO isn't initialized.  The
0x0 screen probably leads to the zero-sized buffer you are catching in
that patch.

cheers,

  Gerd
