9cpu/Feedkey broken

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start Feedkey in ACME-sac
2. 9cpu -h some.cpu.server
3. look at console

What is the expected output? What do you see instead?

I expect to be cpu'd into the target system, instead I see the following on the 
console:
-> proto=p9any role=client <-
proto=p9any
start p9any
findkey '!password? user? proto=p9sk1 dom=vmware'
[Bufio] Broken: "Bus error"


What version of the product are you using? On what operating system?
built from hg code version: changeset:   226:ffec88ce5fdb

Please provide any additional information below.
I'm trying to cpu to a vmware image on the same machine, but this has worked 
under normal 
Inferno using wm/feedkey, so I'm not sure what's going south.
