don't let me discourage you from upgrading, 3.3 (and 3.4) is much better than
3.0.3.   However the dom0 memory squeeze problem can usually be solved
by setting dom0_mem in the /boot/grub/menu.lst of the dom0 on the xen.gz
line to the ram you want to dedicate to the Dom0 (somewhere between 512M
and 1024M)   then be sure to set dom0-min-mem (in /etc/xen/xend-config.sxp)
to the same value   

(you can also set dom0-min-mem to 0 in older versions of xen and in newer
versions of xen there is a enable-dom0-baloon value you can set)  

either way, once you stop balloning, (something that in a dedicated
xen server environment I think is a bad idea anyhow, much like this
'memory overcommit' people are on about lately)  lots of your
stability problems will go away.
