err... please read 2.6.12-bb2-skas0 in my previous post instead of
2.6.12-bs1-skas0. I did try too many patches lately :)

Sorry can't do (trust me I'd prefer too :)
I just browsed again openSSI.org and we need their 1.9.x version which,
of course, is based on 2.6.10.

Concerning 2.6.12-bs1, I already tried it before but, since I couldn't
recall what went wrong, I re-compiled the guest uml kernel using this
time various options (support for SKAS and/or TT) and re-tested the
whole thing

Each version was compiled by doing a 
make ARCH=um mrproper
make ARCH=um defconfig
make ARCH=um menuconfig (to edit changes between trials)
make ARCH=um linux 

Summary of results

SKAS + TT			./linux-tt-skas
hangs  
				./linux-tt-skas mode=tt		hangs
TT only			./linux-tt 				hangs


In all cases, boot hangs on sleeping process gets unexpected signal 10
This is the original bug I bumped into and which led me to try the skas0
approach to escape any TT mode related problem

SKAS 	(dyn linking)	./linux-skas-dynamic		
	(stat linking)	./linux-skas-static	

These are useless since there is no skas support in the host kernel

I don't know if this info helps but it may spare others useless
compilations at least.
