Actually I had seen that Ubuntu bug when I prepared 0.5.3 but decided
not to take action on my own.

Searching for "libvfd" shows that only a few other projects (linuxmce,
minimyth) use this code as well, but there is no trace to an offical AMD

If "libvfd" was a 3rd party library that we could dynamically link
against it would be much more easier to include only the "bridge"
driver, like we have ones for svga, xosd...

In my response to the Sourceforge ticket I put the rules I apply for new
drivers. They address most of what you mentioned above.
