Heylo,
I made some updates to the new fbdev-directfb which may have corrected
some problems with accels not being loaded quite properly. Now all
the DirectFB global symbols are in their own sublib. (Thayne, for
some reason this new sublib is not building in .libs, but out in the
open, though it seems to install/work just fine.)
In addition, it is no longer necessary to have the directfb source
in order to build. Recent DirectFB versions seem to install the necessary
headers to compile the target. So the --with-directfb configure directive
has been coopted to set the directory in which DirectFB driver .so files
are looked for. Unfortunately, the Debian -dev package does not yet include
these header files, but as the packagers catch up I expect it will
be possible to build with a .rpm or .deb of DirectFB. If you have
a directfb-internal directory in your include path after installing DFB,
odds are you can compile this just fine.
Still no luck with my Riva 128, but if anyone wants to try it, preset
your fbdev to a 16bpp mode and try stars. The screen should not clear,
but the stars should be there. If you see a black rectangle painted
at 100,100, then you have made it farther than me (currently fillscreen
is hacked to only draw a small rectangle.) GGI_DEBUG=255 output should
contain something like the following:

^^
You must be in 16-bit mode, DFB doesn't support pseudocolor, and only
on a few cards is 32-bit supported.

(Stats are obviously broken in the Riva driver.)
This driver should only be considered about 50% complete, but give it a try
if for no other reason than to ruin your uptime record :-) (actually, although
I have had to ALT-SysRq-k the app a couple of times, it hasn't hung me up yet.)
Enjoy.
