Michael suggested that I try add the define to rename the struct in compat.h,
as this will remove a lot of compat code from all the drivers.  What do you
say?  All that #if stuff can build up to make quite a mess.

I've tested with kernel 2.6.12, all the x86 drivers compiled fine.  I think
there was an I2C change in kernel 2.6.13 that I had to include some compat
stuff for.
