postgres odbc with crystal reports server xi on linux

Is anybody successfully using postgres with Crystal Reports Server XI R2 on
linux ?

I'm able to connect with Windows ODBC just fine.

I can also get data out with a test program on linux so I know my driver and
odbc.ini are good.

The target environment looks like this:
    * White Box Enterprise Linux release 4
    * Crystal Reports Server XI R2 (evaluation copy)
    * postgresql-8.2.3
    * psqlodbc-8.2.3

I know Crystal doesn't officially support postgres, but since I'm using ODBC
shouldn't it work anyway?

Any suggestions?
