No, it was uncompressed. GRUB 0.97 doesn't use LZO compression.
Anyway, we need to check savings on the GRUB 2 core image, which is much
shorter than stage2, and factor out the decompressor size. My gut
feeling is that block sorting algorithms like lzma and bzip2 would be an
overkill, and even switching to gzip would be only marginally useful.
