I tried this on my 15" AlBook (one of the new 1.5GHz ones), applied to
Debian's 2.6.9.  It suspended and resumed fine (and quickly!), but
after resume I noticed that images (in Mozilla and the root window)
would become corrupted if obscured and made visible again, e.g. by
switching tabs, or by moving between a full and an empty workspace.
