I made the unfortunate decision to leave the 800 mhz patch on my Pre during the upgrade. I then removed it due to instability and reinstalled it. Stability and speed returned but Universal search went away.

I then tried the Webos Repair Utility without uninstalling the 800 mhz patch first. Well, that was bad. My phone went BONKERS (remember that candy?). Ultra Laggy, amazing instability, Pandora wouldn't work, the phone got HOT and my batter drained 90% in 6 hours.

It is currently visiting the doctor, but I thought I'd warn others of my perilous adventure.
