[9fans] p9p venti w/ raw partitions

[a]

Is anyone running venti with raw disk partitions on Unix? I've got a
nice large disk to dedicate to it, and would like to do it without
needlessly imposing another fs, if possible, but am running into
problems. The blocker now is fmtarenas is complaining that it
"can't determine size of partition" for raw disk partitions.
