1) Russia intervenes to support Hungary in the 1848 revolution, and wins. Hungary is established as an independent nation and Russia annexes Galicia. Austria is reduced to Austria, Bohemia, Slovenia, and Trieste.
2) Frederick William IV accepts the "crown from the gutter." Germany is unified. In OTL the Frankfurt Parliament ended up supporting the Großdeutsche Lösung, but Austria refused to join because they did not want to give up their land in the East. In TTL, when they had already lost Hungary and Galicia, they would be willing to do so. All that they would have to give up is Trieste. As a result, a more liberal Germany is established containing OTL imperial Germany, Austria, Bohemia, and Slovenia.
3) Italian revolutionaries are more successful in trying to unify Italy as Austria doesn't intervene against them. They can also point to German unification and gain more support that way. Likely they would succeed, but if they don't you can delay the French revolution of 1848. Without Napoleon III France likely wouldn't intervene against the Italian rebels leading to an almost sure chance of success.
4) In total, by 1850, Italy would be unified, Germany unified including Austria, and Hungary Independent.
