[rsbac] UML with RSBAC hangs at boot

I'm trying to compile an UML with RSBAC. That's what I did: I used 
a freshly unpacked vanilla kernel (I tried 2.4.30 and 31), unpacked the 
RSBAC 1.2.4 kernel version independent code, applied the RSBAC 1.2.4 
patch, applied RSBAC 1.2.4 bugfixes 1 to 4, applied the latest uml 
patch I could find (2.4.27), applied the fixpatch I found at 
http://uml.rsbac.org . Then I did:

make mrproper ARCH=um
make xconfig ARCH=um
make dep ARCH=um
make linux ARCH=um

The UML compiles fine, but it hangs when I try to boot it. I use a 
RedHat 7.3 filesystem, and the UML hangs on a line with the command 
"sleep 1" in the rc.sysinit. It's just after the "Press I for 
interactive mode" line is displayed.
I run the uml with the "rbac_softmode" kernel option on.
If I turn off RSBAC in the kernel config, the UML compiles and runs just 

CONFIG_RSBAC_INIT_THREAD is on, but turning it off doesn't change a 

I also tried to compile an UML from kernel 2.6.11 but I got the very 
same result...

I managed to compile and successfully run an UML from the kernel sources 
I found at uml.rsbac.org (RSBAC 1.2.2 on kernel 2.4.26), but if I try 
to use this command:
switch_adf_log RECEIVE NETOBJ 2

I get this reply:
Error: Function not implemented

That's why I'm trying to compile a more up-to-date version of RSBAC.

My host's kernel (2.4.31) uses the SKAS mode patch.

I hope somebody can give me a hint about what to do... If you need more 
infos (my uml kernel .config or whatever) just let me know.

Thank you in advance.
