Since there was a request for what steps were used to get it working, I'll post what I did (basically what was suggested):


Downloaded through browser:
http://nmacleod.com/nokia/n800/micro...-4.2007.tar.gz

opened xterm:
# sudo gainroot

Backed up libflashplayer.so:
# cp /usr/lib/browser/plugins/libflashplayer.so ./

unpacked tarball (this overwrites libflashplayer.so, above, so no need to rm it first):
# tar -xvzf microb_flash-4.2007.tar.gz -C /

changed directory and created symbolic link:
# cd /usr/lib
# ln -s libplayback-1.so.0.0.4 libplayback-1.so.0

then exited root and created the mozilla symlink. Note: I do not have microb installed, but do have minimo installed. The plugins directory did not exist, and I haven't actually tried flash with minimo yet. This step should have absolutely no effect on the opera performance but I did it anyways.
# cd /home/user/
# mkdir .mozilla/plugins/
# ln -s /usr/lib/browser/plugins/libflashplayer.so /home/user/.mozilla/plugins/libflashplayer.so
