Well, today you're in luck! You're touching a driver that requires no
special hardware, so you should be able to test it.

I think you can try using the mem= kernel parameter (see
Documentation/kernel-parameters.txt) to restrict your system memory, and
then try using that unreachable portions of memory for phram. You can
try this driver as either a module or built-in. For the former, you can
specify the parameters during modprobe time, or later by writing to
/sys/module/phram/parameters/phram. For the latter, you can specify on
the kernel command line or in /sys/module/phram/parameters/phram.

Let me know if you have any more questions about testing your patch.
