If that doesn't help (and I'm skeptical, as the crashes fixed by that
package appeared to occur on the way into suspend), can you try
different settings in /etc/defaults/acpi-support

Coming back from resume with no video might indicate a need to alter
some of the workarounds there, such as saving (and writing back) PCI
config space, or saving the video state.

Options such as

SAVE_VBE_STATE=true
SAVE_VIDEO_PCI_STATE=true
POST_VIDEO=true

Might all be tried.

(NB: I need POST_VIDEO=true, but not the other two on 945GM. If your LCD
fades / bleeds to a funny colour with any of these, pull the power. Mine
does without POST_VIDEO, and it probably means the LCD is being fed a
bad signal, you shouldn't leave it like that).
