cloud bookmarking app or method working with del.ic.ious/gmarks?
There's an add-on for Dolphin Browser HD which can sync with Google Bookmarks: Bookmarks to SD.

GoMarks for Google Bookmarks is also in Play Store.

Do try Xmarks too if you need cloud bookmark sync (not limited to Delicious, Gmarks). It has an Android app as well as Dolphin add-on too. But, its not free on Android.
