I tried this rom for a few days last week. Too many things not quite right for me to use it as an everyday but a really, really good starting point.
Things that didn't work were video playback didn't work and song playback wasn't possible.(on 3 different players no less!) even the stock player, which also showed multiple copies of each track on my SD card even though there weren't.
I could't remove any files from the external card either and a few apps didn't display properly (showed in a tiny window and didn't show the entire app).
Minor niggles but for me, enough to make me go back to Darky for now.
Can't wait until HE gets the Samsung stock ROM to play with and port to the SGS!
