Please, don't do so! I do find the hex values in the backtrace *very* useful as I'm using 'objdump -wdr vmlinux | less' quite often to "browse around" in the kernel binary. Grepping for addresses from a backtrace works quite nicely this way. Having to lookup symbols and do base-16 arithmetics in the head (or a shell, for that matter) would only slow down this process. So, please leave the hex values in place. They do help a lot -- at least in the non-kASLR case.
Regards, Mathias
