This limitation is mostly irrelevant because Debian only supports 64-bit UltraSPARC, so the only case we have to worry about is the disk from an older to a newer machine. As for the original question, I can't speak for sure, since I'm not a SPARC porter, but it only seems logical that a 64-bit kernel (which, again, is what they all are in Debian) will be able to address more than 2GiB of swap. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
