I'v pushed a patch from Mr Hristo to the same effect. I guess it's still in 
the queue. I haven't received any review for it yet. (...Andrew?)

| CONFIG_RD_LZMA=y
| CONFIG_INITRAMFS_COMPRESSION_LZMA=y

  That is because, when multiple options are set, CONFIG_RD_GZIP is checked 
last in the usr/Makefile.
  ...
  # Gzip
  suffix_$(CONFIG_RD_GZIP)   = .gz

Hope it helps.
