Ok, I say it once again. What is contents of your php5-sybase package?
There is MSSQL.SO - so I would understand a bug asking for building separate SYBASE extension.
In debian/patches/119-sybase-alias.patch we aliased SYBASE functions to MSSQL in EXT/MSSQL/PHP_MSSQL.C and php5 is built with (see debian/rules): --with-mssql=shared,/usr --with-pdo-dblib=shared,/usr
And this was introduced in php 5.2.4-1. If you spent same time checking what I said (really reading changelog.Debian would be sufficient) as you spent writing you long reaction, it would save your and mine time as well.
