So the usage patter seems to be:

- I use __alloc_bootmem() to reserve memory
- I export a structure that contains data about this memory (location
and size mainly)
- In the init of my framebuffer driver I use the data in that structure
to configure the hardware
- I map that area of memory to userspace when they try to mmap() this fb
device

Can you comment on this?
