Following bluetooth chips can have their bdaddrs permanently modified:
CSR bluecore4-rom
CSR bluecore2-ext
Some Broadcom chips can work, their bdaddrs can be temporarily modified.
You should prefer CSR bluecore4 chips over any other chips (some CSR bluecore2 chips and some Broadcom chips do not work reliably).
Warning: most of the CSR dongles from ebay/dealextreme don't work because they are counterfeits!
