Maybe this is a little better?  I talked with Bjorn and willy on irc about 
this and there are some other approaches we could take.  I still think domain 
support is a separate issue from the additions in this patch, but there are 
definitely other ways to export this stuff to userspace.  One would be adding 
sys_ioport system call to ia64 that would allow reads and writes to arbitrary 
I/O ports (not just legacy ones) coupled with exporting the legacy memory 
base address in /proc/iomem somewhere and letting users map it in /dev/mem.  
Doing things that way wouldn't help platforms like ppc though, and the API 
would be a bit more confusing (more places to poke to find the info you 
need).
