KernelTrap: High Memory In The Linux Kernel

Through an explanation about memory management in Linux on the Gentoo Wiki, I was lead to an article on KernelTrap about High Memory In The Linux Kernel. Though I'm still not sure, this leads me to believe Oracle compiles the kernel with the CONFIG_HIGHMEM4G=y switch on and thus the 3 GB RAM for user space application should be in place. However, I'm forced to test this to make sure. :)
