wake from sleep problem in edgy on Powerbook G4

[PrivateUser132781]

Since upgrading to edgy wake from sleep has been unreliable on my Powerbook G4 1.25GHz machine. It worked perfectly in dapper. The following problems occur:
(1) strange screen artefacts on wake (stripes accross screen etc. - this vanishes when xwindows returns) - always

(2) refusal to wake from sleep (screen remains blank, switch to terminal doesn't work, only control-command-power resets the machine, i.e. hard reset) - sometimes

Unfortunately I no longer have access to the G4 hardware. Unless someone else can reproduce this I suppose we should let it go. Thanks.
