Works for me with DBD::Sybase 1.07_01, DBI 1.607 and Sybase ASE 15.0.3 Dev Edition, with the original order of finish() and rollback(), except that I had to add syb_chained_txn  => 0, into the %attr because otherwise I got "Stored procedure PerlTest2 may be run only in unchained transaction mode."

Maybe there's something spicy going on with your mix of CHAINED/UNCHAINED mode, AutoCommit status and whatever's inside the stored procedure. I used just 

create procedure dbo.PerlTest2(
 @id integer = NULL OUTPUT,
 @SomeParam varchar(100)
)
as
begin
 INSERT INTO test (stuff)
 VALUES (@SomeParam)
 SELECT @id = @@IDENTITY
end
go 

Grant Execute on dbo.PerlTest2 to test 
go

sp_procxmode 'PerlTest2', unchained
go

Update 2009-09-17: tested with newly built DBD::Sybase 1.09. Works correctly as well.

Update 2009-09-17 number 2: you can get the 1.09 for ActivePerl 5.8 by ppm install http://jenda.krynicky.cz/perl/DBD-Sybase.ppd
