nvidia fails on register_ioctl32_conversion with kernel 2.6.14

[David Liontooth <liontooth@cogweb.net>]

A git patch from 6 September 2005
(http://www.grmso.net:8090/commit/5dd42c262bd742fa3602180bbe5550b4828de8f3/)
removes the functions register_ioctl32_conversion and
unregister_ioctl32_conversion.

Building or inserting the module nvidia-kernel-source 1.0.7174 on the
new vanilla 2.6.14 using gcc 4.0 I get

nvidia: Unknown symbol register_ioctl32_conversion
nvidia: Unknown symbol unregister_ioctl32_conversion

The changelog for the experimental nvidia-graphics-drivers (1.0.7676-1)
was last updated on 29 Aug 2005 and doesn't mention these disappearing
functions.

I don't see anything on the NV site.  Am I missing something obvious, or
didn't this make it into an earlier kernel?
