Same here. The only difference: It is not a vanilla 2.6.32, but a Debian
based 2.6.32-5-686 with only these things changed.

Do you have the space between "," and "115200"? I use:

   kgdboc=ttyS0,115200 kgdbwait

It works as expected.

I order for kgdbwait to work, it must be after kgdboc. That's what I
found out the hard way. ;)

This one is wrong for 2.6.32.

Other than the space above, I do not see a big difference between your
setup and mine. Perhaps, the space is the problem?
