I moved away from using ioctl's for doing bridge stuff and used 
sysfs instead for the newer API's in 2.6. The problem was that
it is impossible to to use device private ioctl's in a mixed
32bit/64bit environment.  If you look at the ioctl translation
code in kernel/compat.c you will see how the bridge specific
ioctl's are translated.  But the SIOCDEVPRIVATE one's couldn't
easily be fixed.
