local var ...

so what's the point of these two assignments to "last" ?

when it comes to addresses for memory mapped registers, we typically use 
"unsigned long" rather than "int"

if this first one fails, we jump to:

looks like 4 NULL pointer derefs.  so you'll need one specific path for the 
first malloc(), but the rest are fine.
