Yes, you did. Thank you for that.

Hopefully we can get this into a release at some point :)

Now, about why this was a problem in the first place:

I'm using an AT91RM9200, Atmel system-on-a-chip with an arm 920T core. This 
processor has lots of I/O registers that can be conveniently read and written 
with devmem. Unfortunately, some of these registers reside at the very end of 
the 32-bit address space, and mapping these registers didn't work when the 
two-page map wrapped around to zero.
