Huh?  The drivers have no additional functionality in 2.0 that didn't
exist in 1.1.5.  The multiple CPU functionality was added in 1.1 I
believe.  The kernel support for multiple CPU existed in 1.x, though it
was not as refined as the support in 4.4 lite, but that should not
affect the stability of the machine on a x86 system.

I think it happens to be luck that it's working.  There are some problems with
the ft (floppy tape) device driver that may be affecting the others drivers.
The newer boot floppies disable that driver unless specifically configured
to avoid this problem.
