Well, first I thought, this would work:
::%s/[01]\+$/\=printf("%0X",str2nr(submatch(0),2))
but unfortunately str2nr only understands base 8,10 and 16. So I used
bc as external command to take care of the binary conversion:
:%s/[01]\+$/\=printf("%X",system('echo "ibase=2; '.submatch(0).'"|bc'))

Christian
