I rebuild my kernel ,I chose extra options which are contact 
 with VESA ：
  
 [*]VESA  VGA graphics support
 [*]Userspace VESA VGA graphics support
 [*]ATI Radeon display support
  
 I'm sure that the vesa frame buffer support option was 
 chosen by default.
 Then I write grub.conf like this:
  
 root=/dev/sda6  video=1024x768M@60m
  
 It is what the document in source tree exactly shows. The 
 system can start up and there is no error message ,but resolution
 no changed .
 Why it would be this? How can I figure it out?
