Why would you write the 32 bit kernel to address virtual memory with a signed 
integer instead of an unsigned integer, especially when (as I recall) the 
current Linux kernel can address 4Gig of memory?

Out of curiosity, could you have 4 Gig of main memory and then use up to 2|4 
*RAM memory as swap by telling the system to treat it as a virtual drive?  If 
it can be done, what result should one expect (assuming a memory intensive 
application)?
