it doesn't work.
after some testing i discover these results:

under 32 bit kernel, command

m-a  -l 2.6.21-2-k7 a-i kqemu

end successfully, but

m-a  -l 2.6.21-2-amd64 a-i kqemu

end with error:
make[4]: *** No rule to make target
`/usr/src/modules/kqemu/kqemu-mod-x86_64.o', needed by
`/usr/src/modules/kqemu/kqemu-mod.o'.  Stop.


under 64 bit kernel, both 
m-a  -l 2.6.21-2-k7 a-i kqemu
m-a  -l 2.6.21-2-amd64 a-i kqemu
fail to compile.
