Update/set/fix Ubuntu splash resolution

Sometimes Ubuntu installation may fail to set a good resolution for splash screen (the one with ubuntu logo and progress bar that is shown while system boots). This can happen for particular resolutions or, in my case, due to an early upgrade to Intrepid (while still in alpha). So it happened that on my 1280x1024 monitor the splash screen was displayed at 1024x768...really poor! The easiest way to fix this situation is to hack the file /etc/usplash by manually setting the parameters for x and y resolution:

# Usplash configuration file
# These parameters will only apply after running update-initramfs.
xres=1280
yres=1024

And then run the command:

sudo update-initramfs -u

Please note that running update-initramfs may bring changes to your grub configuration file (menu.lst). This means that it would be good practice to back it up before running the update and to check for any possibile change before rebooting the system.
