More sizes for vmlinuz-2.6.25-2-ixp4xx, from actual compression tests:
   1365048  existing file in /boot
   1351528  gzip payload
   2841208  uncompressed gzip payload
   1256640  upx/nrv payload
   1218888  upx/nrv payload after filter (relative subroutine call)
   1018940  upx/lzma payload
    978628  upx/lzma payload after filter (relative subroutine call)

Add start.S plus 1KB for decompressor to get final size for nrv or lzma.
[*Assuming* that documentation for start.S is complete and correct!]
nrv decompresses faster than gzip; lzma decompresses a couple seconds slower
on a 133MHz XScale-IXP42x Family rev 1 (v5l).
