temporarily disable RCS keyword expansion

How do I temporarily disable RCS keyword substitution on checkout?

I am converting from CVS to SVN and I have a convert/verify script. I run
the conversion and then I checkout the most recent sources for all branches
and trunk/head from CVS and SVN. I then walk the directories and calculate
MD5 checksum so I can spot missing files, added files and differences.

The problem is that I'm getting false positives for some RCS keywords. CVS
seems to like a different date format than SVN.

In CVS, I seem to be able to block subsitution from the client via adding
"-kb" to my checkout command (yeah, there's probably a line ending issue
too). In SVN looks like only the property on the file controls this and
there's no way to tell the client to forget about RCS subtition just for
this checkout.

So, is this possible or is propedit the only method?
