Just recovered my computer from the same problem. The bug is NOT in the usplash package. it's the AMD ATI driver called fglrx. Instead you should use for the moment the opensource driver. The following is a howto:
1. get into recovery mode (when grub loads, press ESC, select recovery mode)
2. choose to get NETROOT from the menu
3. sudo apt-get remove --purge xorg-driver-fglrx
4. sudo apt-get install xserver-xorg-video-ati
4. sudo reboot
