Saw this a few days ago and didn't bookmark it, found it and am about to try it. Seems to be the only solution for guiminer ceasing to work at random times-caused by video kernel/driver failure etc etc...
 As GUIMiner is the ONLY one I have used(newbie) I am going to attempt to use this with poclbm...not so good with command line tho lol
I'll get back with you, thanks for putting this out here.
