Is it possible to have larger SGA size on Red Hat Linux 5.5 running Oracle 10.2.0.5?

We recently added 512GB to our physical memory. On redhat linux 5.5 running Oracle 10.2.0.5.
We played around with shmall and shmmax. But ran into ora-27123 error.

kernel.shmall = 268435456
kernel.shmmax = 274877906944

According to article id 1241284.1, some settings have to be changed.  

Is there any Official Oracle document on what are the changes we need to make to have a larger SGA size?

Howdy, Stranger!
