The built-in shell is busybox's doing an ash impression, I think. Somewhere I think I saw a bash package for the ITs. That may help.
Edit: cvmiller beat me, and with a link, too.

But for ssh sessions to the 2 computers I access regularly, I just use the cpu-monitor with the dropdown command list, and a few scripts. Also lets me easily start ssh tunneling and VNCviewer.
