You already said you edited /boot/grub/device.map, so I'm not sure.
Could you please send me the output of:

  sh -x /usr/sbin/grub-mkconfig -o /boot/grub/grub.cfg

vga= doesn't work with the 32-bit boot protocol now used by GRUB 2.  You
can use GRUB_GFXPAYLOAD_LINUX (see 'info grub' in unstable; there are
caveats), or you can edit /etc/grub.d/10_linux and change places where
it emits 'linux' and 'initrd' commands to 'linux16' and 'initrd16'
respectively.
