Downloaded, configured and compiled qt-embedded-free-3.3.4 with arm-xscale-linux-gnu/gcc-3.4.1-glibc-2.3.3 toolchain
mounted by nfs, export QTDIR=/path/to/new/qtdir, commented out export QTDIR in /etc/init.d/opie and started it
worked like a charm, but not that is the point, the point is that it works faster
i dont know if because of gcc or qt, but the difference is impressive, even opera started to move like on my desktop.
Did someone try qte3?
