installing 7.0-release from .isos: endless mfi status msgs on console

[Jacob Yocom-Piatt]

am setting up a new fileserver on a poweredge 1950 and installing from 
the freebsd 7.0-release .isos but can't read anything on the console 
since the PERC 5/i or 5/e card(s) are dumping status messages to the 
console non-stop (~1000 lines / minute).

is there any way to disable these status messages so that i can get 
freebsd installed? AFAICT there is nothing broken with the battery on 
either of the PERC 5/i or 5/e cards installed.

cheers,
jake
