Tony,

   Maybe there's time for one more push to Linus?  The function
ia64_pci_legacy_write() returns 0 for everything except errors.  This
return value gets sent back to the user from pci_write_legacy_io(),
making it look like every write fails.  The trivial patch below copies
the behavior of the SGI sn machvec and does what would be expected from
something implementing a write() function.  Please apply, Thanks,

	Alex
