Considering that any BSD will not have KMS for quite some time
(do they?), this sounds very cruel. Is it really such a big
pain to keep the code around?

OTOH, BSDs are stuck with pre-TTM Nouveau until they port GEM
and TTM to BSDs. How much more will it cost to BSDs to add KMS
to the list of mandatory kernel features... rnoland and others,
any comments?
