There have been several viral genomes completely sequenced.
Sequencing of E. coli is about 50% done and C. elegans is about 1%
My understanding to the yeast chromosome III result was not quite the
same as yours. There are many genes identified that had great
similarity to other known genes. However there was also a large
percentage of the predicted coding regions that had no match with the
existing sequence databases. I believe the percentage of coding
regions with no similarity was around 40%. This is similar to the
percentage of EST sequences from human brain as well as C. elegans
that have no similarity to the sequence databases.
