Just done it:
mkdir /home/zaurus
Install the following (I did this to / on my C750, ymmv):
opie-sh_1.1.6-r0 from new feed
oz-compat_0.5
oz-compat-opie_0.1
xlibs_4.3.0-2_arm.ipk
xbase-clients_4.3.0-2_arm.ipk
xqt-server_0.0.9_arm.ipk
rxvt_2.6.4.1
blackbox_0.65.0.1
xqt-startup-scripts_0.0.2
xbase-etc_4.3.0-2
Restart opie (to get the new icons)
Use make compat to make XQt server compatible (choose list rather than file).
[the line below is not a typo it is supposed to be /.*]
cp /home/zaurus/.* /root
rm /home/zaurus/*
rmdir /home/zaurus
Start XQt (can't remember which icon).
Hit menu key, select 'Full Screen'
Use fn-tap to get Blackbox menu.
Use shift tap to select items on the menu - random?
Seems to work fine, time for bed.
