yes, Fedora evolves fast ;)

It doesn't sound like you did much wrong, the 178 updates shouldn't have 
borked your xorg.conf.

No, if you tell the system to work at 16 bit, it should respect that.

My guess is your xorg.conf isn't quite correct. I suggest you post the full 
file here. 

Also, it would be useful to look at your Xorg log file. You should find it 
at /var/log/Xorg.0.log. It might contain hints as to what is going wrong.

For reference, I've pasted my xorg.conf below. You will see in the Screen 
section I have sub sections for various color bits and with various 
resolutions. I have my default depth set to 24, but I see no reason why you 
should be able to have something similar but with your default at 16.

(Note, you cannot use my file directly, as of course it refers to different 
hardware, I just post it as a working example... For instance I have an 
nvidia graphics card and use the nvidia binary driver. You I think are using 
the vesa driver ? )
