A mini_livecd 64bit was never requested so far. An other reason was to limit the amount of LiveCDs.

What I would do:

Install SL55 64bit from installation CD. Install only a minimal set of packages. Boot the freshly installed
system. Take the rpm list of min_livecd 32bit and remove/add rpms on your system to fit the rpms installed on
min_livecd 32bit. For example

wget ftp://ftp.scientificlinux.org/linux/scientific/livecd/55/i386/mini_livecd_SL55_2010-06-17_rpmlist.txt

rpm -qa --qf "%{name}\n" | sort > my_list
sort mini_livecd_SL55_2010-06-17_rpmlist.txt > new_list

cp /etc/yum.conf /tmp/yum.conf
echo multilib_policy=best >> /tmp/yum.conf

rpms_add=$( diff my_list new_list | grep ">" | cut -d" " -f2 )
yum -c /tmp/yum.conf install $rpms_add

rpms_remove=$( diff my_list new_list | grep "<" | cut -d" " -f2 )
yum remove $rpms_remove


Nevertheless, I've just built a mini_livecd 64bit. Download mini_livecd64_SL55_2010-06-24.iso from

http://www.livecd.ethz.ch/download/testing/55/x86_64/

It's not tested, but you may want to give it a try.

Cheers,
