latest cvs & previous snapshot are compatible ?

After testing the combinations of new/old kernel & new/old server,
new/old kernel can start hello server and L4-Linux 2.0, but could
not start L4-Linux 2.2 server which I compiled by myself.
Please ignore my previous report saying "even hello server cannot
work". It seems that I used a staled floppy. Sorry!

The messages displayed are following. Messages are read by eyes,

It seems that both messages are similar, the difference 
between old/new Fiasco does not matter. I'm wondering if
I miscompiled L4-Linux 2.2 - I will reconsider.

By the way, I want to check on 486 PC. The PC I used for
compiling is Pentium machine, and the compiled kernel seems
to be for Pentium and not for 486, how could I compile
the kernel for 486?
