Getting Dual Head Display on X40 series

Would love to know if anyone has managed dual head display on X40 with Fedora Core 3. sankarshan at randomink dot org is the mailing address.

I have received some inputs on this, but based on them I believe some clarifications need to be put into this post.

[1] Dual head is always possible with ATI cards on the laptop. Most IBM/Lenovo Thinkpads don’t ship with ATI (I am one of those lucky few who have ATI on the R51) but with Intel ones.

[2] I am looking for dual head or even the configuration where the same screen is available on the laptop and projector. I know this is not the classical definition of dual head.
