That would make sense. Give it a non-ipath-related name and require that
all architectures which wish to run this driver must implement that
(documented) function.
And, in Kconfig, make sure that architectures which don't implement that
library function do not attempt to build this driver. To avoid breaking
`make allmodconfig'.

In what form is this chip available? As a standard PCI/PCIX card which
people will want to plug into power4/ia64/x86 machines? Or is it in some
way exclusively tied to x86_64?
