Dapper complete system freeze---could be 'ati' driver or epiphany browser

[Sean Hammond]

P.S. I tried switching my driver from ati to vesa in xorg.conf, but
then on starting x, the monitor would report 'signal out of range',
and I had to change it back. Maybe there is something I can do to fix
the signal out of range and use vesa, see if ati is the problem?
