According to a reader over at The Tech Report, Newegg has recently restocked the second generation 80GB X25-M SSDs -- but has not listed any other second-gen Intel drives. The "G2" 80GB X25-M is substantially more expensive than the first lot of Intel drives. Newegg is charging $350 for the currently available 80GB, and The Tech Report notes that the first batch ran about $230.
Naturally, Intel has included a fix with the newly available drives. If you have one from the previous production round, you can find Intel's firmware update utility here.
