Not that I know of. The control file fields are described here: http://www.debian.org/doc/debian-pol...rolfields.html

A workaround could be to install the conflicting files in /usr/local, and set /usr/local/{bin,sbin} first in the PATH in your .profile file.

Another workaround could be to call your file modprobe.new, and include a post-inst script which renames the old one and either symlinks or renames the new one (symlink is probably better), and a postrm (or prerm) script which does the opposite.

(BTW I though the reason modprobe (the installed one) didn't work was because of a missing depmod? Which, IIRC, needs Perl to work? Something like that?)
