I've read the forums on building a custom iso, I've read as well that there will be no official build of a 7.1.2 iso, but I do need one

The 7.1 kernel is the 2.6.9-42.0.3 and I need to boot with the 2.6.9-42.0.10 (7.1.2 kernel) to use the 3ware 9.4.1 driver for my 9650SE card ...
One would say to ask 3ware for the driver, I did, but by the time I get an answer, I would have finish building my own iso

I don't want to add any custom features, all I want is a 7.1.2 iso
If anyone could show me the way please ...
Thanks
