Hardware clock in Sparc32 is based on the year 1968, not from the start of 
century. Currently hwclock reads year 2006 as year 1974, fix attached.

I included also the MMU fix required for correct no-fault mode handling for 
userland faults, please apply.

I installed Debian 3.1r1 from scratch using the system emulator, OpenBIOS, 
and CD image. Network is not working and some programs segfault, otherwise 
everything works well.

Did you apply the attached FPU patch I posted one week ago as well? With this 
patch and your patches all programs I tested did not segfault any longer.

I forgot it, indeed the segfaulting has gone.
