PSP homebrew developer Mathieulh tipped us off today to let us know that a new Popsloader binary with full support for building multi-disc PSone EBOOTs is due for release soon.

Essentially, this means that when converting multi-disc PSone games for use with custom firmware on the PSP, users will be able to store and compress all the data into one EBOOT file, rather than building a separate EBOOT file for each disc.
