Below is the patch to get the netatalk (appletalk) package working with
M68K/linux.

First you must patch the kernel include/linux/atalk.h.  This is already
fixed in 2.0.30 so Jes, please make sure this is included with 2.0.30.

Second, you must patch the netatalk package. (I borrowed this patch from
the netatalk homepage for SparcLinux patches.

Then recompile the appletalk module and then recompile the netatalk
package, and everything should work.

Thanks to Jes and Geert for helping me find the information to make this
work.
