I added some more analysis there.  Yet, I don't know how/where to
fix it.

As a (temporary) hack, you might apply the following patch to your
AVR(!)-GDB source tree before compiling:

--- gdb/cli/cli-cmds.c~ 2010-07-27 22:14:24.000000000 +0200
+++ gdb/cli/cli-cmds.c  2011-12-19 14:42:14.000000000 +0100

+  low &= 0x800000 - 1;

   print_disassembly (gdbarch, name, low, high, flags);
 }
