I don't know yet. Yesterday is the first time I've tried to compile kernel
with 2.96 CVS, it failed in floppy.c (but that bug was multiplatform and has
been fixed since, so today after rebuilding the package and fixing some tail
call things I'll recheck).

In 2.3.xx I wrote a new ioctl32.c stuff so that a kernel module may
register/unregister its ioctl translations and have their handling in itself
(this was done exactly so that non-integrated modules can do that).
The only pre-condition is that the ioctl is not SIOCPRIVATE+x, because the
ioctls are identified by ioctl number and if it is overloaded ioctl which is
used by a bunch of other modules for different things, then the translation
layer does not know what to convert.
