I don't have a 2.6.13 kernel handy to try, but on my test
system I don't have this problem:

test1# uname -r
test1# zgrep IKCONFIG /proc/config.gz 
test1# zgrep REGPARM /proc/config.gz 
# CONFIG_REGPARM is not set
test1# ifconfig cipcb0
cipcb0    Link encap:IPIP Tunnel  HWaddr   
          inet addr:  P-t-P:  Mask:
          UP POINTOPOINT RUNNING NOARP  MTU:1418  Metric:1
          RX packets:13811 errors:0 dropped:0 overruns:0 frame:0
          TX packets:402 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 

I'm using a fairly old ifconfig:

test1# ifconfig --version
net-tools 1.60
ifconfig 1.42 (2001-04-13)
