Please tell me the output of:

  A) A *patched* Linux being loaded by "linux16" command, using the
     patch in:
     http://lists.gnu.org/archive/html/grub-devel/2009-06/txteL9T65YdVL.txt

     This could be what you already provided in
     http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=535026#43
     except your followup comment "vesafb is not picking up the right options"
     contradicts that (linux16 *is* the old loader, and it is supposed to
     work.  If linux16 doesn't work, we have an entirely different problem).

  B) Linux (patched or not), being loaded by "linux" command, using the
     GRUB patch in:
     http://lists.gnu.org/archive/html/grub-devel/2009-06/txtFlQanGk4Pv.txt
     *plus* the patch I'm attaching.

In both cases, I need both the screen_info dump and (if available) vesafb
output.

Btw, you can also contact me on IRC (nyu @ irc.freenode.net / #grub).
