Ok. I discovered, the negative values appear if the ram is more than 2 GB.
If i reduce the ram, the values seems to be correct.

There were bugs (23717, 24092) which are marked as closed since Dec. 2003 and 
NETBSD 1.6.4_RC4 ! This seems to the be same Problem i have with Version 2.1.

sysctl gives

with 2 GB RAM:
hw.physmem=2147020800
hw.physmem64=2147020800

with 4 GB RAM:
hw.physmem= - 67571712
hw.physmem64= 4227395584

which is the same wrong value discribed in Probelm Report 23717 and 24092
I use port i386, Netbsd 2.1 fresh installed from CD, Kernel GENERIC,  

Now the questions are:

Where are these values and the functions used and can this cause an instability of the 
system?
I don't know where hw.physmem is the used all about.
What functions must be patched?  
I´m not an developer so i asked obove questions.

Thank you for answers and 
best regards.
