-nomap forces OFP to avoid memory mapping for file access.
While memory mapping is very efficient from a performance point of view, it can quickly fill all available virtual space, causing various memory allocation errors or even driver crashes or freezes.
This switch is especially important for users with display adapters with large amounts of VRAM (128MB or more), which reserves a lot of virtual addresses in the application address space for themselves.
