Thanks for your reply, Raleigh. Found that the PC card bluetooth adapers would cost around $40 each. Meanwhile, I also found two interesting possibilities which, if workable, would also cost around the same:
1. MSI combo wifi/bluetooth PCI card at:

The description seems to tell me that this MSI pci card could replace my present IBM High Rate wifi pci card, and would provide the bluetooth capability.
2. Hitachi PCI card bluetooth antenna

This description seems to say that if I connect this antenna to the Aux socket in my IBM wifi pci card, this antenna would supply me the bluetooth capability. It even shows how the antenna cable can be squeezed into the pci compartment, without having to thread it up into the LCD interior.
Anyone care to comment? Thanks.
