Since I currently only use an OpenSUSE 10.0 system, I think it must be 
the vesafb driver, since at installation time no graphics card was 
known, so I thing it defaulted to vesafb.

Under FB I got good results without doing anything, but under X there 
are sometimes problems with FB: multiple images, sometimes 
color-separated or something else. And Full Screen did also make some 
problems then. Since I'm quite happy (at the moment) with the situation
I did not really delve deep into the whole framebuffer thing.

Another thing still emerged: I have a Twin-View setup (TV-Out mirrors 
the entries of the Desktop, but only the upper right 1024x764 pixels.
earlier I had to switch resolutions before starting mplayer in order to 
get a fullscreen picture which filled the TV, and not the Monitor. Later 
I came to patch mplayer (so I had to specify -vo xv:full=0 to default it 
to 1024x768), but with the new version (since pre8) things have changed: 
now mplayer per default uses 1024x768 (which is the resolution of the 
TV-Out, but the monitor is at 1280x960). So I had to patch it anew. 
Still working, though... But it always gives me a bit the creeps when I 
have to recompile mplayer, since I have to re-insert these patches 
(there's also dvdnav (for sony's new copy protection), which is also a 
PITA to patch) and another short patch for automatically calculate the 
exact aspect ratio (to find out if a movie is in 2.31:1 or 2.37:1, I 
hope you get my meaning). And currently I find it hard to insert x264 
and xvid. *grmpf*

But in short time I'll set up the system entirely anew (LFS), and 
hopefully with all headers installed properly, all will run smooth 
eventually.

Once can still hope, but judging from my experience as programmer with 
hardware drivers (SCSI, USB, Motherboard Chipsets) and the current 
situation with the drivers (as lately reported by Dave Airlie with the 
ATI ones) things don't seem to improve soon :(
