with XFree86-3.3.3 it works now fine (and fast !) on my
Olivetti Echo Pro 133 E Laptop. In X86Config Section "Device" i set only the
options VideoRam 1024 ChipSet "clgd7548" ClockChip "cirrus".
Before XFree86-3.3.3 i had to set ChipSet "clgd5436" and lot of more options
, which disabled the accel functions of this chip
