Hi Claudio,
I tried LEM mini-distro (http://www.linuxembedded.com/lem.php3 ).
It uses UPX to compress XF86_SVGA down to 1.1 Mb. But it has a drawback that
some may found severe : when a UPX-compressed executable is run, it makes a
temp file of about the size of the original executbale (for XF86_SVGA, it's
roughly 3 Mb).
If you have many UPX-compressed executables, or if you are short on /tmp
size, it is not very usable.
