Hello Jan,

Sorry for the delay, I'm busy with other stuff too.

Thank you for the report, I check the revision guide and everything seems ok. I
would like you to test attach patch. I think it does only what you did + updates
the documentation.

Please can you test that patch?

Signed-off-by: Rudolf Marek <r.marek at assembler.cz>

This patch adds support for the Celeron 4xx based on Core 2 core.

Thanks,

Rudolf
