In short - no I didnt get it working.
ABI support was available in sme56 and I attempted to install our 3rd party application on a sme56 test machine. I encountered a lot of problems - old cobol environment. It wouldn't work. Dont know that ABI wasnt working fine.
To get a 601 solution I was looking at downgrading the kernel, and with lack of success on the 56 application build - I chickened out.
Also the supplier expressed a desire to keep the application on a seperate machine - I couldn't resist his requests - we were on a budget!
Recompiling is fairly easy - you need the source for the kernel (its stock in 2.4.18 - I think) and do a standard kernel build.
Good luck - it you get it going on 601 please drop me a line
