Haven't tried, but some googling indicates it won't work - or at least 
it will require some hacking on your part.

The JrSX lacks a math coprocessor, which is unsupported with all recent 
official Debian kernels. You will need to compile your own kernel, 
patched with unofficial math emulation patches.

The JrSX is reported[1] to not support PXE network booting (but possibly 
the alternative RPL - I maintain an RPL daemon for Debian and am happy 
to help with that if need be). The Jr may have same limitation as they 
probably share similar bios routines.

The JrSX uses XGI Volari Z9s graphics chip which is currently 
unsupported by Debian AFAIK. The Jr uses SiS 550 which should work.

The ethernet driver for the JrSX was reported to not work with DHCP. 
Maybe works with more recent kernel - but then again, most recent 
kernels may not yet have working FPU emoulation patches.

If your plan is a few machines, I would recommend something better 
tested (personally I use VIA Eden motherboards), but if you like the 
challenge and/or plan to roll out many machines, it makes sense to try 
if the Jr has enough horse power, and if not, then if the JrSX is 
possible to hack to a working state.
