Niall has a good point here... This was actually a requirement, (limiting
datatypes) to keep some developers from getting "too fancy" on the Oracle side
in one environment, another has to do with some of the issues I've seen with
certain applications using the new Oracle version through Reporting Services,
(anyone with .Net apps out there, anyone, Bueller, Bueller? ")) It can be a
bit buggy still, where the old standard of OLEDB, even though they do complain
about it, has been stable in any environment I've used it in...
There is something to be said for these two points though- Do you have a
requirement to support a wide variety of datatypes and do you have the luxury
of installing the Oracle client on the SQL Server.
Good points, Niall...:)

I don't see why you'd be slammed for that, it's a perfectly sensible approach.
I'm interested that you recommend the MS OLEDB provider though rather than a
current Oracle one. The former doesn't support all Oracle datatypes
particularly well (or in some cases at all). It would of course require a
client install on the sql server which may be beyond acceptability :(
