That would (should?) work if you also set $GRUB_GFXMODE to the desired mode (which resulted in strange effects for me). I'm using "GRUB_GFXPAYLOAD=1680x1050x8" instead with the attached patch (based on the patch in [0]) that I keep in /root and apply after every update of the grub package. WARNING: due to some recent changes in the grub package the patch needs some refreshing, but I'm not familiar enough with diff/patch to regenerate it. Use only if you know how the resulting grub.cfg should look like.
