  [trident] xserver goes into infinate loop

Status in X.Org X server:
Status in xserver-xorg-video-trident package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: xserver-xorg-core-dbg

  Added Additional comments about recreating this BUG in Hardy Alpha-3
  in comments below.

  Ubuntu version 7.10 Gutsy xserver-xorg-core

  When launching X at anytime, usally right off the start. Ie right
  after X launches and splash screen occurs.

   /usr/bin/X goes into infinate loop consuming 99% CPU.

  Verified by booting to single user, starting sshd, and letting boot. As soon 
as screen goes blank,
  login via ssh and run top.

  This occurs on a Toshiba Satellite Laptop 1800 exact model PS181C BIOS
  version 1.2 (floppy is dead, cannot upgrade BIOS)
