Here is a small guide to install new drivers Vu+

First make a backup copy of your current drivers, copy all the files in
/ lib/modules/2.6.18-7.3/extra

When new drivers are available, take the tar.gz file and unzip all the files in
/ lib/modules/2.6.18-7.3/extra
and replace the old drivers.

At this point you can restart the dec.

If the image is rebooted correctly the new drivers are compatible with your image, if it does not start means that the drivers are not compatible and must wait for an updated image

In this case, to restore the old drivers, just connect with ftp and copy the old drivers, which have been backed up previously, in:
/ lib/modules/2.6.18-7.3/extra
