I thought the big concern was finding the USR_* addresses, since they
dependend on where the kernel was loaded.  The hack to get those via
adddress arithmetic on __ps_strings has been in libkvm for (squints at
old source tree) what, at least 2 years now?

(I asked Jason about doing the same thing on i386, as a short-term
solution for the the very large KVA support added to the i386 port

If that's not the big concern, what is?
