Preallocate 256 KiB of bootmem memory for the PS3 FLASH ROM storage 
driver.

I still very much dislike the #ifdef xxx_MODULE in main kernel code.

Me too, but there's no other reliable way to allocate it after boot 
up...

At the end of the day, is it realistic to ever use a PS3 without the
storage driver ? I would suggest just allocating those 
unconditionally.

If you don't plan to (a) boot into GameOS or (b) update the kboot 
kernel, then the answer is: yes, you can live without the FLASH ROM 
driver, and save one promille of RAM.

In that case, why not make it an early_param, and only change the 
default based on the config varables?   It sounds like I might want to 
reclaim this memory even if I compiled in the driver.

Statement (a) is because one has to write the flag to say don't' boot 
OtherOS to go back to GameOS (or reset all defaults) I presume.
