  done all that, no change.  i first rebooted with the new ati driver,
didn't help.  i rebooted and manually added "nomodeset" to the kernel
command line (and verified it was there via /proc/cmdline), no
difference.  then rebooted normally again, still no change -- stuck at
1024x768.

  this is the relevant snippet from dmesg from that last reboot:
