In what LSP of the 1.2 CDK?  Mark has been predominantly discussing
the 8240/755 Sandpoint and providing pointers to software that doesn't
represent integration of the 8xx software on the CDK.

Is this a problem in one of the MPC8xx LSPs of the CDK?

I'm travelling and don't have an 8xx LSP handy, but there was supposed
to be sufficient space allocated here to prevent this condition.  Thanks
for the note and I will check the software to ensure this is correct in
the MPC8xx CDKs.
