sys/proc.h:

1.233     ad        343: /*
1.273     ad        344:  * These flags are kept in p_flag and are 
protected by p_lock.  Access from
1.233     ad        345:  * process context only.
                    346:  */
...
                    353: #define        PK_32           0x00040000 /* 
32-bit process (used on 64-bit kernels) */

So you can check if that bit is set in the current proc's p_flag member.
