No at the current time ther is no 64 bit version of Opera. But they did list the following proceedure for Ubuntu:
Procedure
1. apt-get install dchroot debootstrap
2. Choose a location that has ample free space (e.g., /usr/chroot32), and invoke mkdir /usr/chroot32.
3. Add that location, $CHROOT32, to /etc/dchroot.conf in the form of $UBUNTURELEASENAME $CHROOT32, where $UBUNTURELEASENAME = {'breezy', 'hoary', 'warty'}.
4. Invoke debootstrap --arch i386 $UBUNTURELEASENAME $CHROOT32.
5. Add the following lines to $CHROOT32/etc/apt/sources.list:
1. deb
http://archive.ubuntu.com/ubuntu $UBUNTURELEASENAME main restricted universe multiverse
2. deb
http://archive.ubuntu.com/ubuntu $UBUNTURELEASENAME-security main restricted universe multiverse
3. deb
http://archive.ubuntu.com/ubuntu $UBUNTURELEASENAME-backports main restricted universe multiverse
6. Invoke chroot $CHROOT32 and dpkg-reconfigure locales.
7. Invoke apt-get update and apt-get dist-upgrade.
8. Outside of the chroot environment, edit the main system's /etc/fstab, adding the following lines:
1. /home $CHROOT32/home none bind 0 0
2. /tmp $CHROOT32/tmp none bind 0 0
3. /dev $CHROOT32/dev none bind 0 0
4. /proc $CHROOT32/proc none bind 0 0
5. /etc/passwd $CHROOT32/etc/passwd none bind 0 0
6. /etc/shadow $CHROOT32/etc/shadow none bind 0 0
7. /etc/group $CHROOT32/etc/group none bind 0 0
8. /etc/sudoers $CHROOT32/etc/sudoers none bind 0 0
9. /etc/hosts $CHROOT32/etc/hosts none bind 0 0
10. /etc/resolv.conf $CHROOT32/etc/resolv.conf none bind 0 0
11. /etc/nsswitch.conf $CHROOT32/etc/nsswitch.conf none bind 0 0
12. For all entries in /media, perform a binding step similar to the ones above.
9. Invoke mount -a.
10. Create a script, $SCRIPT, that contains the following lines:
1. #!/bin/sh
2. /usr/bin/dchroot -d "`echo $0 | sed 's|^.*/||'` $*"
11. Invoke chmod +x $SCRIPT.
I'll try this and let you know. Haven't done something like this before. If it doesn't work I guess 'll install 5.10-32
