It's fine with me. As i said, I had a gzip decompressor in early
linuxbios, and we can look at getting it back. I just stole the one from
the kernel. nrv2b is nice, I understand, for the romcc section where you
don't have many variables to play with, but it's been so long since I
looked at the gunzip code that I have no idea if this is true.
