I spoke too soon... doing a dump over ssh using ipw with the new 
changes:

ipw0: ipw_cmd: SET_SCAN_OPTIONS failed, timeout (error 35)
ipw0: ipw_cmd: DISABLE failed, timeout (error 35)
ipw0: device timeout

No dump device or dump.  This Thinkpad T42 has FreeBSD 8-stable and can 
be configured for some testing if needed.  Thanks for your work on this!
