8961, 8929, 7105, 601 Errors All On Same Table

We recently restored a database from a...

windows 2000 x86 sp4
sql 2000 enterprise x86 sp4 stand-alone
all drives hosting sql databases are SAN attached, write-caching is enabled

server, to a...

windows 2003 enterprise x64 sp1
SQL 2005 enterprise x64 sp2 2-node active/passive
all drives hosting sql databases are SAN attached, write-caching is enabled

server.

We are experiencing data corruption on different tables in different databases. So far, we have always been able to quickly resolve the issue by simply running a DBCC DBREINDEX against the table. However, we are unable to resolve the issue with the latest occurrence. Any help would be greatly appreciated. Here is the output (or partial output in some cases) of various commands:

DBCC CHECKDB ('DATABASE_NM')

DBCC results for 'main_notes'.
