http://grub.enbug.org/Authentication 密码相关配置文件格式
引用:
Basic authentication support has been merged in SVN trunk revision 2529 (2009-08-25)
Example grub.cfg snippet:
代码:
set superusers="user1"
password user1 password1
password user2 password2
menuentry "GNU/Linux" {
set root=(hd0,1)
linux /vmlinuz
}
menuentry "Windows" --users user2 {
set root=(hd0,2)
chainloader +1
}
Superusers must be set to enable authentication support.
Every superuser can go to commandline, edit menu entrys and execute all menu entrys.
GNU/Linux can be booted by any user.
Windows can be only booted by user2 and user1 who is a superuser.
password command only supports unencrypted plain text passwords.

从时间上看当前版本 1.97~beta* 貌似已支持开机密码。
另一方面，ubuntu 那帮家伙忒猴急，把一个一个安全问题推送给他们的用户。
用虚拟机试了下，配置中需要添加下面红色部分，
superusers=""，引号可选，非必要，
使用明文密码，貌似暂不支持 grub 方式 md5 密码，
qemu 没问题，kvm 下键盘失效(可能是偶这里 kvm-70 版本太低所致)
代码:
insmod password
set superusers=user1
password user1 password1
