It shouldn't be too hard, given that freebsd ports to another platform 
already exists (i386), and kaffe has been ported to alpha, and there is 
a fairly well working alpha-netbsd port.

Basically, take a look at the linux & netbsd files under config/alpha/*, 
figure out the right settings for SIGNAL_ARGS and friends, and figure 
out the right setting for  SP_OFFSET by running developers/sp_offset.c. 
Try to get the interpreter to work first, without shared libraries. 
Looking at config/i386/freebsd2/md.h, I guess you may need to save the 
floating point registers in the signal context, so you may need to write 
some assembly there, and do some research.

Oh, and read the documentation on 
http://www.kaffe.org/documentation.shtml , especially the porting guide. 
  And come back often to ask questions ;)

good luck,
