This means that your cmdline override worked.
It also means that OSI(Linux) was enabled, which means you were running 2.6.22.

this also means that you are running 2.6.22, which had OSI(Linux) enabled by default
and wasn't smart enough to change the line above when there was a cmdline override.

2.6.23 is just as dumb, but with the opposite polarity:-)

The patch for 2.6.24 will be a little more clever, and I'll
probably send it to 2.6.23.stable as well...
