I have the same problem and i have a small workaround:

After boot i have to restart the tablet-browser-daemon.

/etc/init.d/tablet-browser-daemon.init restart

After that i can start the Browser.

After boot <ps -ef> "/usr/sbin/browserd -s xxxx -n browserui" is not in the prozesslist.

After restart it was listet. But why it dont starts at boottime?
