video problems with YDL 3.0 and iMac TFT 15"

[Michele Passante]

Hi, I've (text) installed ydl 3.0 on my iMac TFT 15".

XFree86 configuration doesn't works. I've downloaded Xautoconfig0.18 
and run Xautoconfig with --safe option (use fbdev). In this mode the 
screen is visible, but with horrible color (8 depth).

Tried to change depth color and resolution, but X server won't start.

Can anyone give me a valid XFree86.config file for my iMac?

Thanks in advance,
