Hi,

Please update the commit message. We're skipping if , "mode_lo->vdisplay 
 > mode_hi->vdisplay". Mention the same.

Also, I think its better to move this check inside "get_lowres_mode()".  
Before returning 1024x768 mode, we could use the same check used in the 
loop, "mode->vdisplay < limit", and skip the test if this is not met.

Thanks,
