I wrote a kernel feature called initrd-archive (One day it will hopefully be implemented into the official tree), that will allow you to use tar.gz archives instead of raw images, and will dynamically create a minix fs on /dev/ram0 at boot. Not only are .tgz's a good shot smaller then a compressed raw image, but the total cost to the zImage is only +~2K. The 2.1 version I wrote also is optimized to cut memory usage down during all this gunziping and untaring.
That said, bzip2 might not be a bad addition for initrd images, and the above tar's, but I doubt it is worth the cost for the kernel. The question is, how much K will the unbzip2 itself takeup....that could be the killer.
If someone gets me a unbzip2 library, I know the rd code well enought to help implement it.
