Here it get's strange :
scotchmobil scotch # dd if=/dev/mem bs=1c skip=536150130 count=2
dd: reading `/dev/mem': Bad address
0+0 records in
0+0 records out

Uhm as far as I know "the southbridge" is is the Intel 82801. There are 
more than one 82801 devices, so I just post all except the USB devices,
