unknown command vbeinfo (changing splashscreen) in 11.04

[Abhishek Dixit]

Hi,
I followed instructions here (also has instructions for 11.04)
http://www.hackourlife.com/how-to-change-default-grub-theme-or-splash-image-in-ubuntu-10-10/

did following
1) sudo aptitude install grub2-splashimages
2) sudo gedit /etc/grub.d/05_debian_theme
replaced line no 157 on above by
/usr/share/images/grub/Apollo_17_The_Last_Moon_Shot_Edit1.tga
new file  05_debian_theme can be seen here
http://paste.ubuntu.com/693152/
the file /usr/share/images/grub/Apollo_17_The_Last_Moon_Shot_Edit1.tga exists.

3) sudo update-grub

Generating grub.cfg ...
Found background image:
/usr/share/images/grub/Apollo_17_The_Last_Moon_Shot_Edit1.tga
Found linux image: /boot/vmlinuz-2.6.38-8-generic
Found initrd image: /boot/initrd.img-2.6.38-8-generic
Found Windows 7 (loader) on /dev/sda1
done


upon rebooting I checked vbeinfo command on grub shell  and
on grub> prompt vbeinfo got
error:uknown command vbeinfo


but upon reboot I did not had any kind of image on the grub screen as
I had expected.
What possibly more is required to be done?
