William,
The theshold for using PAE is actually far lower than 4GB. 4GB is the total memory address space -- split that in half for 2GB for userspace, 2GB for kernel. The OS cache resides in kernel space -- after you take alway the memory allocation for devices, you're left with a window of roughly 900MB.
I'm curious, how do you get 1.1GB for memory allocation for devices?
